Call Kaitlin @ Reliant Mold Testing.

I am "testing the waters" before fully adding the remaining two into individual LLCs, as this is my first time doing this. 

It’s only $99 and is a bore to get through, but teaches you everything you need to know for your test.

But since the core is made of particle board I was sceptical and put a smaple to the test.

you will want Handyman insurance, and as @Glen Morrow stated, you will not be allowed to pull permits, per state law, you would need a contractors license to pull permits, and technically to do work on a 1-2 family dwelling. to get the license you need to complete a 12 hour training, and pass a test, and have appropriate insurance, Quite expensive insurance at that.

@Wesley Jensen work with the tenant to have the area properly inspected for mold, possibly even having a mold test done.You may need to check your state's Legal Entry rights to do it while the tenant isn't there if they will not cooperate.

Unless we note otherwise in the listing information or disclosures, we fix everything that is broken or not functioning properly, but we have had several recent requests that are expensive and I'm interested in your experience in handling things like:- this roof is old and we're worried that we may have to replace it (was inspected by roofer and determined to be functioning properly)- there are screens missing from some of the windows and we would like you to add them- we're concerned about the drainage and would like you to add gutters- the AC unit is old (age disclosed in disclosure docs, was tested by HVAC guy and running fine) So do you budget for this type of concession, do you "meet in the middle" or do something else?  

I passed the state test with no problems, I think Raymond does a good job of teaching.

Change the mailing pieces and A/B test your response rates.

Being a real estate agent is not something you can approach casually and hope to start receiving "capital" if you actually want to make money you have to go balls to the wall and create a full blown business (which is what I'm doing right now, actually still waiting to take my RE test, this is just what I've observed).
