From there I accepted and negotiated to have the seller cover the cost of replacing the roof.

A DSCR loan could definitely work, especially if the park’s cash flow can cover the debt.

Ensure you collect a proper security deposit (typically one month's rent in Florida) to cover potential damages.Your plan to increase rent next year makes sense given rising costs (taxes, insurance, and maintenance).

I really like the fact that you made a profile with a picture first before your first post.

I hope you have a lot of cash available to cover the FTC fines. 

I'm making a healthy downpayment cash by doing a cash out refinance on three of my established properties that I know can cover the debt service handily.

At $2450, it will cover those expenses.

The mortgage would be $5,200 so I would cover the other $3,200.

I used a HELOC to cover the down payment, appraisal gap, and furniture, allowing me to enter the STR market without depleting cash reserves.

Insurance typically covers only the directly damaged area, not undamaged flooring, even if it's continuous.
