I am unsure if I could purchase a property through an LLC/SL based in Spain and what would be the taxation using this system.

@Jason Brown - I'm a CT based investor, flipper, and property management company owner.  

Based on the knowledge and experience you have, would you consider this strategy if you had to go back at my age?

My name is Monty, and I’m based in Freeport, Florida.

In the end, buyers would overpay for the actual property based on earnings.

Yes, as S-Corp owners deferring salary into a Solo 401(k), you must still pay FICA taxes (Social Security & Medicare) on the deferred income since FICA is based on W-2 wages, not taxable income.

I contacted ALE solutions on Friday through their housing request form and just resubmitted with a longer term minimum based on what you stated here.

The guest house has STR rental history but the other two units would need to be based on projections. 

Does anyone here have any idea (based on data), if the home prices will be going up or down in 2025?

@Jaycee Greene I am looking to buy a primary residence while I am based there, then turn it into a rental once I PCS again two years later.
