We recently added 3 AirBNB vacation rentals in Costa Rica to our investment portfolio, and my advice is to consider:1 - all potential expenses (it is higher than you might think for AirBNB, depending on location, upscale or not, outside management, etc), especially start-up furnishing expenses2 - high and low seasons because occupancy may not be consistent throughout the year. 

Our house is in Spring, Tx and with the growth that's been going on in Houston, I really think the long term housing market is pretty solid.Monthly Expenses:Mortgage Payment - $1,042.85 (Includes P&I, Insurance, and Taxes)HOA Dues - $45Repairs/Maintenance - $257 (Roof, HVAC, and Water Heater are from 2016 - plumbing is all galvanized)Property Management -  $160Total Expenses - $1,504.85Estimated Rent - $1,600It's a pretty thin estimated monthly margin of $95.

It may be more expensive (mine was $400) but it's worth it! 

Fixing that would not be too expensive...compared with the cost of tunneling to find out where the separation happened ($$$$).Lender won't approve loan for house with foundation issues?

Right now I'm feeling overwhelmed, excited, nervous, and impatient.

I was surprised, yet not surprised how expensive it really is.

Around my parts you can expect to pay $300 for something like that, so number 1 can get expensive if you do many offers. 2 is not scalable as you run out of favors, and 3 requires some level of education and/or experience. 

Just going off the data you have given, the park is running a 91% expense ratio.

I looked into some turnkey properties as I’m investing out of state (the Boston market is a tough one) and some of the tk providers gave me numbers that looked fantastic and were similar to the ones your showed...but as soon as I plugged in the other expenses, I was looking at a cash return of 3%!

I would budget maintenance expenses as well as capEx.
