I'm of course going to ask the owner if the unit is legally a triplex and I did confirm on atlas.phila.gov that it is RM-1, which is good but wanted to see how I can confirm through online records that it indeed has 3 units and not 2.

Off market - Online How did you finance this deal?

And the answer is always the same :-) There is no way to accurately do this...too many variables and moving parts, plus it varies too much from one locale to another.You need to find a really good General Contractor and pay him to walk the property with you....over and over....until you feel really comfortable estimating yourself, and that should take years.Alternatively there are online calculators (even one here in the tools section) but I would not rely on them for the reasons listed above.
