We don’t feel these are necessary, especially considering that the property already passed inspection when we bought it.We're concerned that we might be getting taken advantage of, and that these costs are inflated or unnecessary.

Also, the incredibly low interest rates and low yearly property taxes (depending on your location) help a bit on the cash flow end.From my understanding, opportunities exist in different cities in Spain, especially when considering distressed properties outside of inflated metropolitan areas (not to mention the alternative ways of acquiring property like judicial auctions, cash purchases, etc.). 

For example: your current interest rate, rental rate, expectation for appreciation, tax benefits, leverage and inflation protection. 

what it sounds like you are asking is illegal in many ways, section 8 laws, local laws, duel contract laws that conflict, there always has been also those out there looking to catch you breaking them,  avoid it, dont offer it, dont entertain it, there is leeway up if the tenant meets certain conditions, say need 1 floor rental, if not rent may be inflated over realistic market, which is what rented at not listed at, keeping in mind sec 8 market rents also include utilities paid, you can usually reach by email fastest, they have set chart, heat type, neighborhood etc, more than listings found online

I think most locals are aware of the history of STRs proposals/cases in Portsmouth, Laconia’s existing restrictions limiting non-owner occupied STRs to resort/shorefront only, VT's local option tax that allows a 1% tax above the state's existing 9% tax, Portland cap on STR permits and increases tied to inflation, and it's also probably a good idea for folks to understand NH's Senate Bill 249, which proposed a "ban of local bans" around STRs and basically died on the floor(?)

I am more concerned with inflation , rising property taxes , increases with insurance , and going bald .  

I am worried that Trump may lose, and Kamala will destroy the U.S. with inflations, her stupid policies that weaken the dollar, the immigration will continue, etc...

That means you may not be keeping up with inflation. 

I personally wouldn't go above the historical rate of inflation (closer to 3%), and always underwrite my deals as 2%. 

This shift is driven by consumers seeking affordable meal options amidst rising inflation.
