Need Help Evaluating a 4 Plex

[Dean I.]

I know, I know, use the search bar . . .  and I will, but I was hoping to get some fast advice while I do, since I will be putting in an offer tomorrow.

This is a Quadplex building in subdivision of other 8 or 10 other Quadplex buildings. Basically, it is an apartment complex, but I am only looking at buying one of the buildings (it is the only one available right now). So far, it satisfies the 1% and the 50% rule, which I know only means that it is worth crunching the numbers more. My plan is to purchase the building, rehab it and do some upgrades, then refinance it and get all of my money back out of it. The problem is, I don't know what it would appraise for. From my understanding, since it is only 4 units, it is looked at like a residential property. The problem is, there is barely anything to compare it to. So how do I figure out a value for the building? I need to know what I can expect to refinance it for after the rehab.

I should also note that I am putting this one under my personal name in order to take advantage of the 30 year mortgage. I also don't plan on living in one of the units. Not sure what all the rules are on all that. This would be my first rental property purchase.

Thanks in advance.
