John absolutely - in the day and age of the internet and google I get 90 percent of my homes all digital.

(One child owns the house, the Trustee of my trust owns an easement around the entire perimeter, for example)I would think a very good argument could be made that the house is worth only 30 percent of its previous value.  

If everything is in pretty good condition then you could have less.In general, if you put about ten percent of the rent amount into the reserve account you should have enough money to fix and replace things when they need it. 

I will check out Matt's you tube videos.I just hope that Costa Rica continues to be......Costa Rica in my life time. 

100 percent seems a little fishy.

@James G.i’m about 95 percent sure the short term rental ordinance doesn’t allow campers/air streams/rvs etc to be used as short term rentals.  

The language is "no greater than 15 percent more"

If you are negotiating a rent raise and are charging a percent of rent as your monthly charge this is also a win for you both.

I have enough capital to make the purchase but I can only handle another $600 per month in overhead to keep me under 50 percent debt to income ratio.
