I could clear $125k in equity if I sold now, would hate for that equity to vanish come spring summer time.

Especially if you can get a few address of properties currently for sale (or recently sold), you can see if the properties and the neighborhoods match up with the sales pitch.

That could happen but that would mean that if he sold a property with a $0 basis for $100K and his gain would be $100K.  

Put pen to paper on a real (ideally, recently sold) property and then you’ll know if you’re likely to make $200 or lose $500.

If you want the house SOLD forget this "investor".

You'll be able to find out how much a bank liened when the property was sold and you could probably estimate monthly payments since then- just use an online amortization calculator.

I was left a piece of property, from family estate, and recently sold it (I could not afford $22,000/annual property + expenses of living). 

@Zachary Stoll, my guess is the Seller (read: Flipper) over-rehabbed it (for the area), but is still hoping to find an owner-occupier like yourself who'll overlook the fact that the sold comps / usual rents in the area do not support the asking price.Over time, its value will tend to devolve to the lowest common denominator (ie. comps that have not had the same level of money spent on them).Right now, the only thing I see going for it is that you'd get to live in a nice apartment (albeit in a sketchy neighborhood?)

I found this little nugget of info in the instructions for Schedule C (Line 1):Installment sales.Generally, the installment method cannot be used to report income from the sale of (a) personal property regularly sold under the installment method, or (b) real property held for resale to customers.

I recently sold my rental condo and I'm now looking to move into multi-family.
