The only other thing I can recommend is that when you talk to them, make sure you are separating your personal relationship and your professional relationship, both internally and externally.

First thing to do is get rid of the, plaster & lath, drywall, greenboard and cement board and substitute a material that is water proof backer.

Construction costs and material costs are cheaper because you are selling a 250k house to a first time buyer, not a 800k house in Poet's Corner.

:) I'm yet to read and watch through a bunch of materials available on this site, but I now confident that everyone here is willing to help!

I have a lot to learn and look forward to networking as well as reading up on all the great material this site has to offer.

As luck would have it, my Architectural practice has specialized in energy efficiency for over 30 years...and I have designed quite a bit using the materials mentioned in the house.  

My question is should I offer the seller more money ($5,000) and say it's for appliances, flooring & other building materials I saw when I did a walk thru? 

I new the other material so well that I knew missing 5 math questions was no biggee... same with section and range questions..

The bathroom floor and part of the subfloor in the hall and kitchen would have to come-up; the wall between the bathroom and hallway and across the end of the hall would be going back to the studs; the common wall between this apartment and the adjacent unit would need to be brought up to current {fire} code; the ductwork for the HRV needed to be replaced; and three of the existing windows had broken thermo panes.We also planned to improve the energy efficiency of much of the envelope during this renovation - the amount would depend upon what we found behind the drywall.What we found:The damage to the subfloor on both levels was more extensive than forecasted and I wasted two weeks, and a few hundred dollars in materials, over the holidays in December trying to remove the smell of pet urine (ozone, enzymes, sealant, etc).
