I would be surprised if it voided the title insurance, but I have never actually looked into it.  

Surprised to see 15 years left on initial term.  

Found out the bank I use for my checking does RE Investing loans in Texas (surprising since they're based in Michigan and I believe they are a small operation), but hopefully I can get some numbers to compare...not sure if it matters that they aren't local

But as you are finding, small inexpensive SFRs for buy and hold sound good on to a beginner, but have unexpected challenges.  

I have ample credit to cover the inevitable big surprise.

Your numbers are not too high, and especially for your first property you want to figure conservatively so your not surprised with negative cash flow on your first go round. 

Surprised your lender didn't catch this.

Don't be surprised to see some BP members appearing on the State of FL unlicensed activity complaints records.

It helps to have the extra capital for carrying costs, unexpected rehab expenditures and closing costs.
