I have at least one BP member meeting me there, but we haven't hammered out an exact date/time yet. 

The permit for this expires 9/2021 so they want me to reach out to The Town of Ouster Bay to try to get something in writing showing that I will apply for the permit when it expires.Does anyone have any experience with this?

HMLs will sometimes charge 1-2 points or a fixed amount.In Texas, there is a form filed in the real property records noting the new maturity date and any other modified terms. 

On the day you close this all could be your problem to deal with, and trashy tenants paying way below market value doesn’t serve you OR them well, so I’d recommend either buying it vacant and clean, or buying it at a substantially lower price under the stipulations that the seller serves 30-day (or locally relevant number) notice to them so that on closing date or soon after it should be vacant.

List out the certain construction items to make by a certain date. 

I have been searching for Multifamily properties of all types online almost everyday for a few weeks now just to stay up to date with the area I live in.

If the existing 'main' MLS in an area wants to get most or all of the local listings, they need to step up, be the most modern, up to date, easiest to use, add value, etc, and not be the clunky 1990s-feeling websites/portals that they currently are.

The lease dictates that they will be in default after 10 days of non-payment for rent, but I wonder if they're trying to draw out the process as evicting them would likely extend beyond the date of lease termination (and be more costly as well). 

I found a house listed as auction on zillow and it does have a auction date listed as 3-12-2020.

FHA is the 3.5% down program, and conventional is the 5% down program. 2) You have to live in the property for one year from the date of the closing.
