Since I was in Texas and I planned on staying there I looked into taking a broker test and I found out that I was qualified and I got a license without taking anything extra.  

Whichever part of the couple is going to be on the mortgage, they need to be able to qualify independently for the mortgage.

Since I was uin Texas and planned on staying there I found out if I was qualified to get a real estate broker license and I was qualified and got a license without taking anything extra so I got a license.

For reserves, I have read that the lender will consider 60% of your 401k as qualifying and I would assume a cash savings would count regardless of your personal intent for it.

Well unless you jump some hoops and have a RMLO do up the paperwork and qualify the buyer etc.  

Also I don't think you can qualify for any mortgage with a credit score under 630 - if you can it will be a VERY expensive loan. 

That will continue to be the case with your transaction providing income to the IRA.I would strongly encourage you to have a qualified CPA or tax attorney review the situation and ensure the IRA is acting in compliance with IRS guidelines.  

This would be my first investment property and my ultimate goal is keep purchasing rental properties until I reach my "freedom number" Also while I'm asking question, how do you qualify for buying so many homes and not having DTI issues?

Since I was in Texas and planned on staying there I checked out my ability to get a broker license and I was qualified to take the test and I got a license.  

I've been looking into the Rhode Island Renewal Plan myself as I would also qualify under the first time home buyer designation.
