Private lending costs more per dollar than conventional, and that cost is usually worth paying once you understand what you are actually buying
The rate difference is the visible part. A private loan priced at 11 to 13 percent against a 7 percent conventional feels like a penalty, but the comparison only holds when both options are actually available. Conventional lenders underwrite the borrower first and the property second. Private lenders underwrite the property first and tolerate a borrower profile that a bank would decline at the desk. That is the transaction: you trade a lower rate for access, and access has a value that does not show up in the rate column.
The number doing the most work in that trade is time. Say a four-unit building comes available at 310k with a 45-day close hard money or lose it. Conventional takes 45 days on a good day, longer on a mixed-use with two commercial tenants, and the seller knows it. The private lender closes in 10 to 14 days. The spread between 11 percent and 7 percent on 250k borrowed for 90 days is roughly 2,500 dollars in extra interest. If the deal has 40k in equity at purchase, you paid 2,500 to preserve 40,000. That math is not close.
The drawbacks are real and they are structural. Points at origination, typically 2 to 4, are a front-loaded cost that bites hardest on short holds. Prepayment on a six-month minimum means you pay for time you may not use. Extensions at 30 days carry a fee and reset your carry cost. If the rehab runs long because a contractor disappears at month four, you are paying 11 percent on a property that is not generating income and burning through the float you budgeted. The lender is protected by their position. You are exposed to the gap between your draw schedule and your actual spend.
The other structural issue is exit dependency. Private loans are bridge instruments. They assume a conventional refinance or a sale within 12 to 18 months. If rates move against you or the appraisal on the stabilized property comes in short, the bridge becomes a problem. The private lender can extend, but extension is a favor, and favors have prices. The underwriting question to ask before you borrow is not whether you can afford the rate. It is whether you have two realistic exits if the first one closes.
What is your planned exit when you draw the private money, and have you stress-tested what it looks like if the refinance appraises 15 percent below your ARV estimate?
