You must maintain a unit as a primary residence - that keeps a lot of pure investors from completing an SB9.3.

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?

Investing in NNN lease (Walgreens, Dollar General, etc are your tenants) is also fairly passive, but you maintain a bit more control. 

Which will also depend on the neighborhood.You want to, "rehab/maintain to the Neighborhood".Most investors go overboard on their first rehab and waste a decent amount of money.

There are also additional costs of operating and maintaining an LLC, like separate bank accounts, annual report filings, tax filings, etc.2.

This allows them to get more capital so they can make more loans without having to grow their asset base, while also maintaining their relationship with the customer through monthly payments.

Typically if demand increases and supply is maintained prices go up. 

If it does go to probate, hopefully your brothers and you can amicably go the informal route vs formal (I've worked with families in both when buying properties out of probate and informal is FAR easier).Since there's no debt on the house, maybe you could sell with financing or maybe you could even buy out your brothers with financing -- that way you maintain ownership and just pay them a monthly amount.

It is important to find something that was properly maintained, with modern plumbing, electrical and roofing.
