Hopefully, if you buy right you may even have some residual equity post your renovation on your FHA Multi Family, you can even consider using some of your equity in a equity line position play or you experience enough growth coupled with the equity that you can refi to a conventional 15, reduce your interest responsibility, get a more favorable rate and climate your PMI, this is a little more complex and requires an intricate series of ballot steps to achieve the ultimate outcome, but very doable.Much luck with your accession and renovation. 

My husband and I plan to travel every summer to cooler climates lol, in our RV, so we'd like something that we could rent out during the summer through a property management company, while we travel.

Your expenses can be MUCH higher or a little lower depending on your climate, county taxes, size of the units, etc...

FL has taken a real beating in the last few years and looks like it will continue as the climate warms. 

We're not too familiar with upkeep given the different climate.

Stepping stones are also really inexpensive, as is gravel but depending on your climate those can become a pain to mow/ weed if the path isn't used much.

Depending on your local financing climate, you usually have to show at least T12 to refinance.

It's the climate.

Admittedly do not have any short-term rentals, but am curious to hear how people are navigating the current climate.
