My loan was traditional loan with a Mortgage company with 25% down.

Your buyer won't be able to get traditional financing, as you don't own it yet, and that will come up in the title search.  

If you are looking near downtown many of the properties are old and may not pass a traditional insurance company's underwriting.

In your name you can go traditional Fannie/Freddie.

Therefore we will need to secure traditional mortgages rather than purchasing outright.

These seem like a gold mind to me in terms of cash flow, but I see several of them in seemingly good condition languishing on the market for months when more traditional homes in the city are under contract within days.For example, here's one such house I'm looking at that is very common around here:Asking price: $52,000908 sq ft, 2 BR, 1 bathNo garage, small lot, siding/roof are <3 years old and mechanicals are <6 years old. 

There is a ton of info here on BP regarding BP, but the basics are to be be all in with the buy and rehab at ~75% ARV, put a renter in, wait your 6 months if refinancing traditionally (there are other options that cost more) and refinance all your purchase and rehab money out.I can't imagine the BRRRR working without the first R, which is Rehab, to force some value into the property.  

The interest rate is only 0.125 higher than a traditional ARM.  

I've tested this approach vs. the traditional route of yellow letters and they outperformed yellow letters by 26.7%.

Do you still qualify for conventional financing and have you spoken to any traditional lenders.
