When pulling the credit report one of the individuals has a high debt to equity ratio (50 %) My fear is what if this High DTI and credit usuage could result in one of the parties defaulting on future rent.

In general, the minimum loans I've seen are 100k (individual properties can be lower if you are buying multiples from the same owner but the loan still must total 100k-ish).

Yes, there are exceptions for significant life events (job change), but each individual must meet the FHA loan qualifications on their own, and the second loan must be for a valid reason, like a job relocation or other extenuating circumstances.

I’ve been working with real estate financials for a while, and I keep seeing one mistake that costs investors thousands: poor bookkeeping leading to missed tax deductions.🚨 Common issues I see:❌ Not properly tracking repairs vs. capital improvements❌ Missing out on cost segregation & depreciation write-offs❌ Scrambling at tax time instead of planning proactivelyI’d love to hear from the group—what’s been your biggest tax headache as an investor?

I was young, poor and a friend who was a broker called me when a dump in an upcoming neighborhood came available.

Each unit is on individual wall/window units and I know from experience those can be a pain to deal with too.
