You have to pay to open and maintain it.Build up your portfolio and then open LLC’s for the properties.

What I mean by mental investment is that thoughout the ups and downs of the housing market and economy ,in the United States , having a income producing property in Colombia that even without tenants or someone staying in the unit it cost me less than$1500 a year to pay taxes, maintain property , and have a company rent the property when I am not there.

.- How would you manage and maintain 4 units?

We're looking for a service that can unify other booking platforms, as well as offer a "canned" and maintained website to do our own bookings. 

I waited until I had several properties just because of the expense of setting up and maintaining the LLC.

I have their website bookmarked now and I'll check them out. 20%irr is really good, I would be impressed if they can maintain that during the next down cycle.

The beauty is that there is a half-mile maintained township road running through the middle of the property.

I have driven by the house, it's in an area that I adore, it has been maintained well, recently remodeled etc. 

The elevator has been well maintained and is currently working.  

I know that well and septic can be costly to maintain/fix/replace.
