I own 20 acres of land valued at approximately $80,000, and I want to build two short-term rental (STR) units on it.For context, my family already owns two long-term rental (LTR) units in the same general area.

@Chris SeveneyI think those that took short term debt, trying to extend their terms, and now that the 10 yr has shot up, it's gonna be very interesting.

Eventually there should be quite a bit of distance between net income in the mortgage. 

@Nick Rivers, where do you feel you are coming up short?  

I've been on this platform for many years and, over the years, I've seen new members linked or part to Mexican real estate agencies posting educational content about investing in Mexico out of the blue shortly after becoming new members and then disappear as they realized that their efforts wasn't giving them the amount of business they were hoping for.

It sounds more like you want to do work for a short time and have success without knowing much.

If your property management company is good and has built an internal maintenance team which has set rates and had strong relationship relationships with licensed contractor which should keep costs in control, you should never need to shop contractors on your own I wouldn't think.So in short, our policy is give us your preferred contractors upfront if you have them, but then we work all tickets to resolution including dispatch, and payment of invoices.This is of course for operational expenses.  

I don't like the short timelines/constraints of 1031 exchanges though. 

I think they contain solid information and will help lay a good foundation as a beginner (Haha, I'm completely new to real estate as well, btw)I'm also going to be reading the following books, and hopefully I can finish all by the end of this month:1) The ABCs of Property Management2) The Advanced Guide to Real Estate Investing3) Long-Distance Real Estate Investing How to Buy, Rehab, and Manage Out-of-State Rental Properties (this might be the most important one to me personally)4) The Book on Investing in Real Estate with No (and Low) Money DownIn addition to reading, I'm consuming crazy amounts of youtube videos, and I'recommend you do this as well.

There is a distinct difference in the law between short term and long term rentals.
