Obviously, the estimate will be a little more accurate for that property vs one where nothing is available except the info you mentioned.

I work in finance and understand how to analyze properties but need local real estate knowledge expertise to make sure my margins are accurate. 

This does not sound accurate to me.

Okay so I’d say 8/10 times I’m very accurate on running comps but then I’ll stumble along a situation that I have trouble finding the arv and was wondering if anyone could give me some insight to help me in these situations1) there are no other comps in area sold with similar bed and bath 2) the house isn’t legally a 3/1 like the other comps but is the same sq ft range.

Do you have a skip tracing or number lookup company that you recommend that gives accurate numbers?

Whether or not this is 100% accurate, it seems like nobody wants to touch this property.

I would probably offer 85k for this property assuming the numbers you posted are accurate

Example if I’m researching markets in areas I’m unfamiliar with what’s the best way to get accurate stats on history?

The rent is around 600-650, there are no recent comps for what it will be worth but a house down the street has a zestimate (I know it’s not accurate) or 75k and that’s what the wholesaler thinks it’d be worth after repairs.

You should be able to put as little as 3.5% down...now yes you will have to pay PMI, but putting 25% down on an FHA loan for a 4 plex does not seem accurate.
