An option could be doing some research to ball park what these estimates would come in at and remove that amount from your offer. 

They definitely dropped the ball and Scott has worked hard to try and remedy the sutuation, although their loan structures changed in the middle.of my deal, and theres not much that can be done now.

We will likely get a realtor in that case… I hope we can sell in time to get the energy efficient passive solar property we want/need, but I’d suppose it’s still possible if we get the ball rolling with a the local realtor soon.

They don't like to play ball with folks trying to invest like this.

It’ll help with the lack of affordable housing so maybe the city would play ball?

So far so good as I have been getting the ball rolling, having bought over a half dozen tax liens so far, and doing thorough research on properties has become more natural with every new lien.But now I must ask: does anyone know anything about TaxSaleResources.com?

IP one I tried to but realtor/property manager says it won't meet the release price since tenant occupied.These PMs low ball everything. 

Nobody has a crystal ball but Grays Ferry is the most depressed of the markets you listed and therefore could theoretically appreciate the most if the neighborhood turns.

Make a large ball of aluminum foil and Scrub grill racks hard.

Personally as a listing agent I have had plenty of low ball offers that are completely ignored because they are so outrageous.
