I focus heavily on the sell side and on the buy side only work with high net worth individuals so the newbie wanting a 400k multifamily with an FHA loan probably isn't for me. 

Quote from @Juan Ruben Cortez: I believe the funding fee is 0.5% of the remaining loan balance, plus maybe another $500 - $1,000 in lender fees. 

Its a tiny loan for any institution.You'll have to get hard bids from a local GC, but maybe $110/ft?

I'd target areas near colleges or transit hubs for affordable properties, and I’d look into financing options like FHA loans or creative financing to make the most of my capital.

They’re requesting what feels like an unreasonable amount of information, and the demands keep escalating.So far, they’ve asked for:A video tour of my home officeCredit checks on me and my partnerCopies of the deeds for every property we ownA copy of my partner’s home lease and utility billsBusiness phone billsA signed letter from the bank verifying our accountsBank statementsHonestly, it feels more like qualifying for a loan than trying to become a customer.

It's the basic formula for selling an online course that teaches you nothing you cannot learn on your own.

Loan interest is deductible based on the use of the loan, not the asset securing the loan. 

Since you will be renting it out you should get a conventional loan.

@Sara Habtom yeah, you will absolutely have loan options.

Is that eligible for an SBA loan?
