Funding Deals with Other People's Money (OPM), Honestly

OPM — other people's money — is the most romanticized and least understood phrase in real estate. Used well, it is simply leverage: borrowed capital, at a known price, secured by a real deal, repaid on a written schedule. Used carelessly, it is how beginners burn the friends, family, and local lenders whose trust took years to become available to them. This guide treats funding as what it is: a product you qualify for, with underwriting standards, costs that belong on your worksheet from day one, and paperwork that protects the lender at least as much as it protects you. No lender in this guide is a prop, and no strategy here involves hiding risk from the person funding it. If a funding approach requires the lender not to understand the deal, it is not an approach — it is a liability with a closing date.

You will learn the real funding menu and what each source actually costs, what lenders underwrite (the deal first, then you), how to assemble a package that gets answered, how to model financing costs into your maximum offer, and how repayment behavior builds — or ends — a funding career. The through-line is simple: lenders are long-term counterparts in a small community. The operators who are never short of money are the ones whose lenders got paid, got informed, and got their calls returned, deal after deal.

1. The funding menu and what each option really costs

Your own cash is the benchmark: no interest, no points, total control, and total exposure. Private lenders — individuals lending from savings, retirement accounts where rules allow, or investment funds — typically charge negotiated interest, sometimes points, secured by a note and deed of trust, with terms set by relationship and deal quality. Hard-money lenders are businesses: faster, more standardized, more expensive, with published rates, points, draw processes, and extension fees. Partners bring capital for a share of profit instead of interest, trading cost for complexity and shared control. Conventional and portfolio loans serve holds, with lower cost and slower, stricter underwriting. None of these funds one hundred percent of everything for beginners, and any source claiming to should be verified with unusual care. Match the source to the exit: assignment needs may be zero, flips need speed, holds need duration.

2. What lenders underwrite: the deal, then you

A lender's first question is what secures the loan: the property's value after repair, your purchase price against it, and the repair plan's credibility. The loan-to-value and loan-to-cost they offer encode their judgment of that security. Their second subject is you: experience, cash reserves for overruns and payments, credit behavior, and whether your package suggests an operator or a hopeful. A strong deal can carry a new borrower a long way; a weak deal cannot be saved by charm, a suit, or a social media following. Expect a first loan to be smaller, more conservative, and more documented than your fifth. That progression is the market pricing your track record, and it reverses quickly — one sloppy repayment reprices you back to the start.

3. Assemble a package that answers questions in advance

Send one organized file: the signed contract, your comp set with the ARV rationale, the repair scope and estimate (bids if you have them), your full math worksheet including financing costs, the timeline, the exit plan and its fallback, your experience summary stated honestly, and your insurance arrangements. Name the loan you are requesting — amount, term, draw needs — rather than asking what they might do. Lenders fund packages that read like decisions already made carefully. Follow up once, promptly, and accept a no with curiosity: ask what would need to change, log the answer, and you have just received free underwriting education that improves your next three deals whether or not this lender ever funds you.

4. Price the money before you promise the price

Financing costs — interest over the real timeline, points, fees, draw and inspection charges, extension costs if the project runs long — go on the worksheet beside holding and selling costs, before the offer, as the flip-math guide insists. On the same illustrative $150,000 borrowing example used in the Learn path, a few points and six months of interest can total well into five figures; your maximum offer falls by roughly that amount or your profit absorbs it silently. Model the slow timeline, not the hoped one. If the deal only survives best-case financing math, the deal does not survive. Bring this discipline visibly to lenders; borrowers who model their own money costs conservatively are the ones lenders stretch for when it matters.

5. Paperwork that protects the lender protects you

Every private loan gets a promissory note and a recorded deed of trust or mortgage prepared or reviewed by an attorney, with insurance naming the lender as loss payee as the documents require. No handshake loans, no borrowed money on a promise to 'do the paperwork later,' no commingling a lender's funds with other deals. Draws follow the agreed schedule with documentation. These formalities are not distrust — they are what let a lender say yes to you instead of to someone safer, and they are what keep a friendship intact if a deal goes sideways, because everyone agreed in writing, in advance, what happens then. If a prospective lender resists paperwork, that is information about the lender, and the wise response is to decline the money.

6. Communicate like a borrower lenders brag about

Report progress on schedule without being asked: photos at milestones, budget-versus-actual summaries, timeline changes the week they emerge, never at the deadline they break. If a problem develops — a contractor failure, a cost overrun, a slow sale — the lender hears it from you first, with your plan attached. Pay exactly when due; if an extension is needed, request it early with updated numbers and a fee you offer rather than wait to be charged. After repayment, send a short closing summary: what the deal did, what their money earned, what you learned. Lenders talk to other lenders. The borrower they describe as 'kept me informed, paid early, zero surprises' has a queue of capital forming behind the current deal.

7. Grow funding capacity the boring way

Capacity compounds through repaid loans, growing reserves, and deals sized to your current proof rather than your ambition. Resist the leap from one funded deal to three simultaneous ones because financing appeared; appearance is not capacity, and correlated rehabs share contractors, markets, and your attention. Keep a lender list like your buyers list — criteria, preferences, past performance both ways — and maintain it between deals with updates and gratitude. Over years, the funding question quietly inverts: from 'who will fund me' to 'which of my lenders fits this deal best.' That inversion, earned repayment by repayment, is the real content of the phrase 'using OPM' — and it belongs to operators who treated other people's money as more carefully than their own.

Worked example

Where beginners go wrong on this — and the fix for each

Three mistakes account for most of the damage we see on this topic. First, skipping the written step. Operators do in their heads what this guide does on paper — a value, an estimate, a decision — and the head version quietly edits itself mid-negotiation. The fix is boring and total: one worksheet, filled in before the conversation that could change it, re-run only when a fact changes. Second, borrowing confidence from other people's results. A stranger's market, exit, and risk tolerance are not yours, and copying their numbers without your inputs is how sound methods produce unsound deals. The fix is to treat every outside example — including the worked example above, which is labeled illustrative for exactly this reason — as a structure to fill with your own verified local numbers. Third, doing this once and calling it learned. The first attempt at any skill in this guide will be your worst one. The fix is reps with records: do it on practice properties, log the estimate against the eventual reality, and let the gap teach you. Within a handful of logged repetitions, your judgment stops being borrowed and starts being calibrated — and calibrated judgment, not any single technique, is what this entire library is trying to build in you.

Your first week with this guide

Do not try to master this in a weekend; instead, schedule five small, finished reps. Day one, re-read this guide and write the three numbers or decisions it asks for, in your own words, on one page. Day two, run the linked tool — the Flip Profit Calculator — on a real property currently listed or recently sold in your market, and save the inputs. Day three, repeat on a second property and compare what changed and why. Day four, find the gap in your own knowledge the reps exposed — a term, a data source, a local rule — and close it in the glossary or the Learn step for this subject. Day five, write the one-page version of your process that future-you will follow, and file the week's worksheets together. Five finished reps teach more than fifty pages of highlighting, and they produce the paper trail your second week builds on. When the week is done, continue to the Learn step matched to this guide — the path orders these skills the way a deal does, and the next skill assumes this one is practiced, not just read.
