I also am very interested in purchasing more STRs, and this is a really low risk way to see if I'm up for it (we have a 2.9% interest rate on our mortgage).My biggest concern is an ongoing plumbing issue we have had.

Margins seem low and the risk seems high.

It looks like a great idea on the surface but the numbers don't stack up from a risk/return point of view as far as I'm concerned (it could be different for you depending on your return expectations).

I know what my ideal life looks like in ten years, unfortunately, I don’t feel like I can have my ideal life now because I am having to stay in the state that I am in until we can move without risk of my husband losing custody of his child, which will be in about 10 years so believe it or not I do spend a lot of time thinking about what I want the future to be like.

Are there any potential risks or downsides I should keep in mind before proceeding?

Risk Management:Every investment has risks, and real estate is no different.

Risk of being the 1, right?

As the risk goes up the cost of money goes up.  

I don’t go above our dti because I don’t want the risk.

However, I don't know from a practical point of view if it's doable 2) Condo vs townhouse vs cashflow: I noticed condos  and townhouses are way cheaper in fort myers FL ( however risk of hurricanes) and maybe more opportunity for cash flow.
