You have more time than money (probably) so use that time to do this work and fix up the room to look very nice.

I will introduce my situation after but I am so grateful for this outlet.

I am always surprised at how many taxpayers don't want to pay for tax planning so they can make informed decisions.

So I really like STRs and thinking about how much to put into it. 

It appears the fee is for each LLC, so if you have multiple RE LLCs, you have to report each one and pay the fee. 

So I'm only one deal into my REI journey.

Amazingly, it is apparently nearly impossible to get decent comps for this so I'm not sure how to approach figuring out whether to outright sell it (and for what price), fix it up as a rental, or market it as a knockdown for the land. 

As others said, check to see if you are legal to do so. 

You will probably have some sort of limit regarding mold/medical, but thee things can turn into a mess, trust me, I manage a lot of units and have done so for almost 30 years. 

The CoC return very likely won't be as amazing as those seen in the US due to the stringent lending requirements in Spain.How's the business been going for you in Valencia so far?
