I don't know NY law, but in AZ, you may send two certified letters. 

If you're going to live in it for a bit and fix it up you can adjust accordingly.

Most listings have 2.5-3% allocated to the buyers agent already written into the listing agreement but you could write into the offer something lower, adjust the offer price lower accordingly and then pay your agent directly instead. 

Click-through rate (CTR) helps measure how effective your ad is at grabbing attention, and if it’s low, you might need to adjust your targeting or creative.

Curious how this will play out in the courts (granted it's LTR) and affect pricing products used for STR such as PriceLabs (which I use but have to seriously manually adjust for very specific reasons).

Income taxes- if needed can you use your 2 year primary residence deduction if a taxable event occurs.13.  1031-  if any part of the insurance claim is a taxable event is there some way to do a 1031 with lenient time frame adjustments?  

Many listings are adjusting their asking price at least once while on the market.

If closing gets pushed, adjust the lease start date accordingly. 

Pricing - If you cannot check your competitions price and adjust yours daily you may want pricing software (PriceLabs probably best for single listing owners/operators). 

Buyers and sellers are still adjusting to these changes.
