Hummm, I’m thinking they are using a tax certificate or something… Not sure how that works, but, if I understand correctly, they pay the taxes for around 7 years and the deed goes to them?

They're considered 1-4 unit properties and fannie mae has a 5-10 loan program.  

I am wondering if I should start looking into licenses or certificates...

Pull the death certificate.

I just spent an hour discussing the entire Mentor Program offered by Cody Sperber's Clever Investor.#1 Total Immersion = $28,000.00#2 Protege Program = $14,000.00#3 Apprentice Program = $7,000.0If anyone out there has been thru any of these, I would really appreciate some insight.

It's the information that is going to be useful to you, the degree or certificate won't matter.

But that doesn't mean that it will qualify for the FHA-203B program.

software program?

WAY less hassle and frankly if you have a crappy tenant 9 out of 10 times the security deposit will end up going to unpaid rent anyway.One thing not mentioned is that you should have the current owner and all the tenants fill out estoppel certificate.  

Although there may be other certificate holders/lien purchasers, sometimes they do not file for the deed/foreclose on the property prior to the statutory period/date, as required.
