The stone elevation can be expensive but will really move a house quickly with the added curb appeal.Some things I like to add for not much extra cost..

Also, what are some other low cost amenities that I can add to my STR that will yield a higher ROI?

What's the location, purchase price, expected Reno cost, ARV, etc.?  

However, I'm unsure about the costs of maintaining the SL in Spain, especially cause I read in some forums that these costs can be pricey..Do you have any views on the above based on your experience?

This allowed me to control renovation costs, streamline operations, and accelerate my investment growth.

Maybe that is gross profit when you sell it, but what about the cost to build it?  

The process from start to finish would take four months and cost ~200k to build, with comps in the area around 355k-lender man said, refinancing would take six months as most lenders wont refinance a property unless its been built for six months, affecting the strategy to get paid out from refinancing quicker and closing out on construction loan-The property would not appraise at comps value, but at the cost it took to build, affecting getting paid out from the refinance.

@Fabio CattolicoFrom my experience, balancing career growth, cost of living, and real estate goals is a smart move.

I have found that they worked really well when it comes to getting better tenants and better rents, and having less hassle, less headaches, and then getting a higher sales price; without paying closing costs or realtor fees.

Attorneys  dont cost, they pay.
