Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

The original quoted rent they were saying they would get was $1575 per side(It's 3 bed 2 bath 1500sq ft). 

Quote from @Daniel Stegelman: The apt. complex has unit has six 2 bed 1 baths and two 1 bed 1 baths.

The income (rent minus management) should cover the costs (principle, interest, taxes, and insurance) depending on the property's price point. 

Not sure if that will be helpful.You could also work with your agent about a big umbrella policy to cover the uninsured parts.

The terms you are looking to offer definitely appear reasonable and you should be able to get these offered out under a white label or table funding (maybe not all those terms at once, but likely covered through different options/programs, even with one lender)

I am looking at a few 4 bed 2.5 bath no HOA properties in pflugerville that I would like to convert into to 8 bed 3 bath properties. 

Vacasa seems like they cover everything which is great for hands off owners, but they charge an arm and a leg.

We are planning to build a 2 Bed/2 Bath 750-1000 sq ft detached ADU.

No surprises about not having enough to cover the balance.
