You could buy the property "subject to" and then refinance into more favorable terms after the first year (a BRRR - Lite) type thing where you could give yourself even more margin on the monthly cashflow to extend whatever is left on the loan back out to 30.

The rot can extend back into the structural members too.

Most leases state showings for releasing is allowed, I know mine do.

If the lawyer decides to follow through with collecting on the fees we can go back to the courts and demonstrate the extended time frame that the entire process took, citing that the probate process for a pretty cut and dried case took nearly two years.

@Allan R.I would have this lady sign a release breaking the lease.

All of my tenants understand they can't extend their leases unless they do that extension prior to my signing a lease with the next tenant. 

*Once you've finished the refi, make sure to follow up with the bank to ensure that they notified the VA and released back all of your guarantee

Afraid we may pay for all this beautiful weather with an extended summer, though.

I would caution that if your tenants are already under contract on a new construction purchase, which it sounds like if they're far enough along that builder is "pushing things longer than originally planned," they may be more financially locked in than they think, so have them produce a release agreement before getting too involved in your sale.
