They said they'd accept a 6 month term instead, but they're not being very forthcoming about what their sales record has been (I asked for the last 12 months just to get an idea, but they ignored the question :( ) and I'm getting a not-so-great feeling about working with them....The home is 2-stories, attached garage, 4bd 3ba, 2269 sqft and sits on a corner lot with a huge backyard (lot is approx .13 acres or 5662.8 sqft).

And then monthly by check or if you don’t trust them certified funds or EFT. 

The agreement is contingent upon the buyer securing financing which I was not able to do and have provided a denial letter.The seller is requesting money for damages because the appraisal came in at the purchase price but needed a heat installed in the kitchen which the seller agreed to install (Not in writing).

Back in 2023, I bought my first U.S. property—a turnkey condo in Myrtle Beach—which I’ve been managing remotely as a short-term rental, netting about $1,000/month on average.

Quote from @Tim Baldwin: @Nathan Gesner, that form should not be used, as it provides for 60 days notice to terminate a month-to-month tenancy, which FS 83.57 only requires 30 days.It was a ten-second search for an example.

At month 70 all leverage is gone.My big question is why?  

Let's assume you accounted for all expenses and have a full $2,400 monthly cash flow.

Typically with houses of this age - you'll need structural folks to dig and install piers into the soil.

However, there are better options than $180 a month and $1000 for a WP site. 

But as far monthly payment you could easily buy a house in a cheaper location have less roommates and the same monthly payment or the same number of roommates and a lower monthly payment.
