First post on BE so hoping this 'test' provide some interesting answers.I have a property in Austin, TX (78704) that's generating 8% CAC returns.  

Use common sense and the mirror test - look yourself in the mirror and ask if you believe what you're saying.Other than that you're on a great path to using 1031s to dramatically increase your RE wealth.

I have worked with my father's real estate appraisal business since I was 17 and will be testing for my State Certification in September.

And the only reason that is, is because I've spent thousands of dollars as well as many months testing and refining the filters that work for me and my other investor clients and would be basically giving away trade secrets for every other investor in my and my client areas to use and drive the price up for our adverts.

You mentioned FHA financing, this is a great program only requiring 3.5% down payment however this would require that you live in the property for one year, also since it's such a competitive market the chances of an offer with 3.5% down payment being accepted is slim (unless you find something off market) since other investors are putting down well over 20% which is much more attractive to a Seller.

Another question...do I need to get my house tested for Lead Based Paint...when I purchased the home there was a lead compliance form which stated that the seller did not have actual knowledge of any Lead Based paints...they sold it to me like this, why would we need to test for it when renting...?

I was testing some of those hardwoods with my key, and they scratch pretty easily whereas I couldn't do that to the laminates. 

Then you can split test your letter and see if you change the font, language etc.

What you are referring to, in a very basic way, is stress testing.

Then you need to take the CA state test which is also pretty expensive.
