Other houses of similar size (2500sqft.) are selling into the low $400k's.  

My understanding is paint is 3 years, carpet 5 years, and you can only charge a portion of that depending on how old it is.  

I have not touched any portions on new construction and GC's to Subs, but I find that these files are the most basic paperwork that a rehabber needs in order to protect themselves from liens, flaky contractors, and what they should expect from contractors.

Once people find out that a unit of this size became available, 4 bed 2 bath NYC under $600,000, people came flocking.

Do you have an area or size of property you are going to target?

Given the high total costs of US financing, it would seem that getting the seller to accept payments on any portion of the total price would be a win.

The seller has significant equity in each property and is offering to carry a second (presumably a portion of the down payment).My question, forgetting about the potential seller carry back for a second, is how will a traditional lender (likely portfolio) look at the forgivable NSP mortgage?  

Whether you could max out with $18K on the Roth portion would depend on your situation and income and would be a matter to discuss with your tax advisor relative to your business tax filing.
