Find houses that have already sold and compare them to what your place is going to look like when it's done.

Look into Homestead funding and see use them as a baseline to compare with everyone else so you ensure you get the best rates.

UPDATE***** 12/19/2018I'm learning a lot, I'm definitely at the end of my budget for this home as it took more that expected to get it to what i felt comfortable and reliable.

A couple of extra points interest on $50k for a few months is peanuts compared to the alternative. 

@Dorian Guin how to the unit costs compare to SFH in the same area (i.e. cost per unit vs. what a SFH costs)  do you have an idea on why the other units have been vacant?

You should connect with a realtor and get access to the MLS.Real estate listings on zillow, trulia, realtor will not be as reliable as what is found on the MLS(or equivalent).Properties on the online sites may have already been sold.Furthermore, properties just recently listed on the MLS may not show up on the online sites until after a couple of days.

I've worked with a couple contractors in the past but need a reliable contractor that can work within a budget and on a reasonable deadline.

Just looking for a good honest and reliable real estate lawyer to be able to look over my deals, offer advice, and create contracts in St.

But I don't think comparing renovations to a primary residence and the sort of work you're going to have to do on a defunct 2-4 MF in a slum are two different beasts.
