Not everything is peaches-and-cream in the rental market in Puerto Rico.

You got creamed because you got in over your head. 20k over on something that doesn't cashflow properly is an impulse purchase not a level headed business decision. 

I believe you will find it will be like day trading if you are looking for the cream of the crop, you will have to be constantly watching what comes out because the steals will be gone in 15 minutes form the time the hot sheet comes out.

Hello Mr Fred RobinsonPlease send me your personal e mail address and I will send you clear working drawings on an "island vent"Having said that,,,a competent licensed plumber will know how to do that correctly for you,,,Gotta be honest here guys ,,,I do not like ,use or recommend air admittance valves ,,ive seen them fail over time and allow raw sewage to enter the structure,,,"Aint a gonna get no Ice Cream and Strawberry Pie from Mama that evenin'" hear????

And how inflation affects you has alot to do with what you really consume, my ice cream has gone up and the carton is smaller, now that drastic!

Once a year we schedule an Ice Cream Social at each property. 

@Todd Dexheimer yes, new builds are getting creamed in every market.

Glass tile is usually more expensive, especially if you go with a boutique tile company like "tile shop,"  but I've usually done pretty well finding good tile selection and much better prices at Home Depot, Lowe's, and Menards.Here's one kitchen I was involved with where the backsplash has whites, creams, and tans, which ties the floor tile, appliances, granite, and cabinets together.As a separate thought, backsplashes are one inexpensive way to really class-up a kitchen and add value to an investment property, plus can make it nice enough to justify higher rents.  

@Bonnie LowI love to eat ice cream, but I do work out is that ok?

Then what you do is go buy two coffee's put the mold in one of them with some cream and sugar and put a lid on it.
