The recommended set back for building is 15’.

I do know that when I use Zillow it automatically gets posted in other real estate/rental sites so you aren't limited to your property only showing up in Zillow.

Obviously, I don't know anything about your finances, so for all I know, you may have a few million in the bank, and this project is just a fun experiment that wouldn't even be a drop in the bucket if it all turns south...but, regardless, you'll want to model out what would happen if this project crashes and burns...As you may know, managing a rental in a D to F area (or even a C area) is usually not recommended (for many reasons), and funding a rehab with credit cards is also usually not recommended (again, for many reasons). ...even highly experienced investors often won't touch anything lower than C grade because of all the difficulties of managing and re-selling them...If you're dead set on rehabbing the place and keeping it, I'd strongly suggest studying up thoroughly on the local rental market and tenant pool (e.g.; rent medians and lower and upper bounds, typical days on market before securing a tenant, local vacancy rates, tenants' typical income, education level, employment opportunities, credit, and rental history).

You could even ask them to do a limited scope appraisal where they generate a light appraisal without a site visit and usually for about half the price. 

@Ross HamiltonAny "revolutionary new real-estate investment service" that expects to bilk me out of thou$ands of dollars, up front, without offering a limited free-trial sends goose-alarms down my back and will get my spidey-sense tingling faster than a hound-dog licks its rear.  

All of that takes many months of time.If your land is 1/2 acre or less with bigger building 5k sq ft and limited parking will be a tough sell most likely.

I’ve been a very passive investor but I’m looking into buying our first rentals out of state and becoming a real estate professional. 

Including, but not limited to:- market- capital required to renovate the four units that need renovation- expected operating expensesFeel free to provide here or message directly.

We have a set limit that we have for credit ratings.

And thats really my question, what do you look for in one set of financials vs another that helps you guide that decision?
