So you can scale that if you want.FHA is for people with poor credit and very little down payment.

I know some mentioned about developing banking relationships and I totally agree with that, so here is what you do. 1) Open a business checking account in the name of your LLC to hold the assets. 2) Deposit your cash into that account to fund the real estate purchases3) After owning for 60-90 days, talk with a local lender about a line of credit against the 2 properties at 60% LTV. 4) After about 30-45 days, have the line open to use if you need that liquidity that you used, but until then you are not paying 7% interest on nothing. 

I am finding that most credit unions will only do helocs on primary residence.

Some of the specifics are credit score, DTI, signed lease agreement, and whether or not the lender accepts rent (house-hack) as income.

Having a stable income and good credit will be foundational in qualifying for a loan.

There are still people out there who only deal with cash, and are queasy about using credit or debit card to make purchases. 

Prop tax ranges from 2.5% in fate to 2.16% in Rockwall city. 2.16% is some of the lowest you'll find in DFW. 

I have the credit and will be funding and backing the loan. 

Quote from @Chris Mason: Rather than starting with one lender and going back to the tenants, another approach would be to work with a commercial mortgage broker who will put the full credit package in front of 10 or a dozen lenders, and see what they come back with.For example, for scenarios like this, I've seen lenders come back and offer a new loan that has a maturity that's coterminous with the lease.

There' s a buyer who will credit me the value of the lots towards a finished and tenanted property in their inventory.
