Work out a deal that way.

I am not expecting things to work out as you implied but prepare a good exit plan.

Get a written agreement from the neighbor that they'll allow it to stay but it must be moved onto your property if it is every replaced.Talk to the neighbor and see what you can work out.

Ultimately STR here may not work out but we do have a desire to buy in the area.  

You can't just HOPE it will work out - you have to run the numbers.You have to make sure your numbers are realistic.

You can find the deal and work out an agreement with the experienced investor.

@Alex GarridoInvesting in Panama City would work out for short term rentals because you could pay for the holding costs and maybe profit nicely while hopefully the value of your property increases over the long term.Unfortunately, it’s illegal to rent for less than 45 days and personally I’d never suggest anybody gets into an illegal business overseas.I’ve come across a couple rare buildings in Costa del Este who have a permit but, as you could expect, it’s reflected in the price.

I would speak to local banks and credit unions since this is where you might be able to work out a win-win financing solution.

The alternative is to find a seasoned investor in the location where you plan to invest, work out an agreement with them to bring their money, time, expertise, relational capital, systems, etc. to a deal you bring to them, and let them show you the process from beginning to end.

On the flip side given how sub to has been mass marketed through the guru / trainer folks you are going to have a lot of the buyers who are NOT properly capitalized  who dont understand how to do these correctly or are just plain crooks and when things dont work out they walk or even worse realize they can just rip rents and not pay on the mortgage this was very common back in the mid 2000s  I got a few interviews with the FBI chasing down folks that did this 20 30 50 times they were criminal enterprises and they ended up in prison..
