After the winter it will be time to assess whether to take another stab at selling the home, or continuing to rent for another year.  

@Patti Robertson I think the OP was talking about property taxes jumping 4K not the assessed value of the home. 

Suggestion:  Try using the BP Calculator to get an accurate assessment of cash-flow. 

I am there to calculate my repair costs, see where I can make more money and to assess the block as a whole.

As investors we like to focus on the cash flow but sometimes we have to take a step back and really assess the uniqueness of a situation. 

The dilemma we're facing is that the foreclosing attorney is insisting that there was a "Sale" that took place, and therefore the transfer tax needs to be paid, which they are basing on the assessed value (I'm assuming).  

The bank will require an additional inspection to assess any possible damage to the property.I have a client who is in escrow on a 4-plex.

It's also possible to have your taxes re-assessed in some instances; you'll need to look into local procedures, obviously.

I'm wanting to know how to assess fair market value, if I'm using the right phrase.  

I would look into MF and specifically, assess whether you want to keep being active or more passive.
