I love this house and don’t want to lose it, I would like to add houses in the long term and build a portfolio. 

Hello Everyone,I really want to learn how to rent my house and aquire another house to rent and so on.

What are the requirements for an owner to hold an open house in Texas?  

The house isn't in a flood zone.

I asked PM to send a bigger cleaning crew vs 1 person as the house is 2600 and needed a good cleaning.

I am owner of my primary house, have excellent credentials, but I am unsatisfied with my passive income and potential to become owner in 20 years of a self financing house elsewhere. 

The house is being sold as-is.

I found a house in Atlanta that comes out to an IRR around 11% when I run the numbers, is that good or should I look for better?

I don't think listing with an agent will work since I am not looking to sell to the general public, I do get these yellow post cards and letters from "CASH FOR YOUR HOUSE NOW" but I believe those are not investors buyers but more bird-dogs looking to get it on a contract to reassign at closing. 

Yes you could buy 1 house cash for $500,000, or you could buy $2,500,000 in real estate with 20% down.When the market appreciates 20%, one would yield you $100,000 while the other would yield you $500,000.This also doesn't calculate the increased cash on cash return you will get with increased rents across all of your properties rather than 1.
