I have a tendency to spend $9 to save $1 on a $10 item I don't need.

You won’t get it from the existing tenant as they magically will not be able to afford an extra $100 a month - so if you raise it you will have no occupancy which at end of day neutralizes rent increase3.

@Richard HowellWhen lending on a primary residence make sure you follow all the CFPB laws such as using a licensed loan servicer, sending compliant monthly statements, collecting escrow and doing escrow analysis as well as sending 1099’s at end of yearLending more than a property is worth you can do but I would advise against it as you are putting your retirment funds at risk

Rehab loans from private money people might have no payments until property is sold or at end of year.

As @Steve K. suggested, the tendency is for governments to reassess the ownership and control of direct coastal areas, a tendency that isn't in your favor.If I absolutely wanted to own a beach adjacent property in Costa Rica to live in and would have no other choice than buying a concession, I'd consider it but then I would only buy if the amount of my investment is equal or lower than the perceived value of the enjoyment I'd get from the property over the remaining time the concession.I assume that you won't buy the lot waiting for the concession without getting it first or you might make the purchase of that or both lots subject to getting the second concession.

I’m looking at that at end of week for sure.  

One thing I've found over the years is that since the employer-matching contributions (for those lucky enough to have one) have a tendency to build up the tax-deferred bucket. 

He also constantly blocking in the other tenant by parking in the driveway despite signs saying not to do so.He has a tendency to urinate on the property (by his moms door steps) and comes in and out during odd hours around midnight.

If you get a loan the appraiser does a current value with tenant in place and a dark value at end of primary lease term if they do not renew the option period.
