The $200k makes no sense and I highly doubt that buyer closes on it. 

Renovated via, paint, lighting, bathroom updates.

I can close quick, but the seller thinks they need more time to find another house to move in, and want a later closing date.

For example, Fayetteville and Jacksonville are some of the only places you might come close to hitting the 1% goal on an LTR, but like other markets (ex: Memphis) where LTR cashflow is strong appreciation is rather weak compared to markets like Wilmington or Asheville where LTR cashflow is poor but appreciation is fantastic.

You must close on those properties within 135 more days. 

Account Closed - let us know how it goes. 

That would probabyl be your biggest hurdle for this type of financing, especially if you're buying a property close to where you live currently.

I'm seeing that mortgage rates have been rising for the past 4 weeks where 30-year mortgages are at around 7% and 15 year-fixed mortgages are at somewhere close to 6.5% now. 

They have to close together per the seller.

Check to see if your old LLC is even still active on the state's roster.I know where I used to have mine (MA), it would be "administratively closed", i.e. dissolved, if you didn't file your annual reports and other paperwork timely.
