My next step is to possible Air BnB proof it with certain locked cabinets and locked storage space that will allow me to easily prepare it for AirBnB on the weekends.

Its important that your agent is able to provide you with a properly prepared CMA so that you know what you are buying is worth what you are paying for it.

Last month I purchased 2508 Ashley Rose Terrace in Henderson for $525k and tested a $2,995 rent rate and secured a quality tenant at this higher rent rate.

That doesn’t meet The “1% test”.  

The last 18 months have been an opportunity for all investors to test our contingency plans and comfort with the current structure of our portfolios.John

We now have people that took a couple of classes on line and bought a couple of books and were able to pass the test. 

We were preparing to send over earnest money and option fee when we were told the sellers were having an issue on their end and may be breaking the contract (it had been 24 hours since all parties signed).  

My question is: what are avenues I can take to better prepare myself for my RE investing journey?

If that doesn't work I would prepare the damage myself and if it happens again get the HOA and owner of that other unit involved.

Pass the test, then you have something to show that you have a bit of knowledge.
