So, after the 2nd month, they have 3 weeks to renew or be gone by the 3 month deadline.

Your purchase will simply have to meet the 45/180 day deadlines for each of the sales. 

I read something about a HUD deadline but can't figure out how to estimate it.

You can even schedule the earnest money deadline for the same timeframe. 

Using that strategy I did an exchange in September and was able to close before my 45 day deadline much less the 180 days. 

.- Not too late, you have up until the filing deadline, but in your case we must amend 2022.- The value is purchase plus improvements. 

There was NO WAY I could turn things around by the closing deadline.

No stress, no deadlines, and i get to keep my control.

I have a GC who is helping out to prep for renovations, and gave the squatters a deadline before we remove everything out of the building and start construction. 

When the new rules regarding STVRs on the island went into effect, there was a 180 day deadline to apply for the non-conforming use certificate for established STVRs and after that only properties that successfully received that certificate OR were in resort zoned areas, were allowed to continue operating their rentals.
