@Katie Berry  give them a choice of a month of gym membership or the rent credit you suggested. 

We are trying to make a choice between using Datazap (3.5¢) per name, vs REISkip (24¢) per name.

Ultimately the sellers get a bit excited about selling for a higher price. 

Since it's not a tax lien sale, but a deed sale, we are ultimately looking to acquire the property anyway.One thing that I do need-  a good RE attorney with knowledge of Deed sales in PA, hopefully Montgomery County. 

Purchase price: $1,150,000 Cash invested: $300,000 Sale price: $1,628,000 Built in 1890, this Old Victorian was converted into a duplex in the 70's by a talented architect who made some unique and extraordinary custom design choices (read vaulted skylights) that made this property truly one of a kind.

Now I'm faced with a choice: Buy for 10k more than the appraised value and get good ROI but start my real estate journey underwater, potentially move into another REI property, go to another bank and hope for a better appraisal price or walk away. 

or you said my hypothesis is wrong, it has to be depreciate 27.5 years and no other choice.
