Tonight I mailed them a letter informing them that if it wasn’t all gone by September 30th I would be disposing of it.

Quote from @Elias Halvorson: You probably can still do an DSCR, with a letter of explanation on the lates if you wanted something now, otherwise you can wait 5-7 months until those lates are no longer in the past 12 months and do a conventional loan  with better terms.  

Some neighborhoods in that area are fully gentrified (German Village), some are strongly in process/nearly fully there (Merion Village), and some are on the cusp and are currently a mix of flips/rentals and more dilapidated properties (South Side). 

I have googled so much and I am getting mixed answers on everything.

If you also rent it out (for more than 14 days a year) during the other years, it's considered mixed use. 

For example DSCR, no ratio, CPA letter, P&L Statement, average bank deposits, 1% down for primaries? 

I realize that once someone creates a letter of intent they can start on the due diligence phase to learn the financials, physical, and legal but what else can I learn about a property before making an offer? 

There is a good mix of investors who like to invest near the university and the other mix do not.

Hi all,I have a single family home I purchased in June 2021 for 200k.Aside from cleaning up the yard, painting, and new water heater there have been no improvements.I recently got a letter that my taxes are going up as they believe the property to be worth 225k as of June 2022. 

See attached Invoice.Through this letter, I hereby request proof that I am indeed the party you are asking to pay this alleged debt, and for proof that there is a binding contractual obligation to pay this alleged debt.
