The bank set me in at 7.1% interest (construction loan short term) This will be a side hustle for me.

If I did short/mid term rental I could do about $3.5K/ month for 10/12 months.

If they are too busy or too lazy to answer a call or send a short email, what else are they too busy for?

In short, yes PS can do everything DM can do and more.

Look into asset classes with stronger cash flow, such as small multifamily properties, short-term rentals, or mobile home parks.

Provide the scope of work done to the appraiser.All you can do is your best, so make it nice and pretty for that appraiser.Especially if you are looking to cash out refinance shortly here.

Caulking a bathtub for a plumber is the easiest job he could charge money for, short of charging to lite a pilot light on a furnace or water heater.  

The beach has taken about a year and the jungle house will take about 4-5 years because we are paying off some seller financing with the revenue from the short term rentals.I would say that I can definitely make more money investing in real estate in the United States than in Costa Rica.

The short answer is No, you don't need it.  

If it's on the higher side you may want to consider it for mid-term or long term rental, but if most stays are below 30 it can be viable for short-term!
