Looks like there will be some grants and loans to assist SFR and duplex owners only in the form of a lein on your property.

I was just thinking today there was all this excitement about VA loan assumptions there for a while when interest rates started going up. 

Texas does have specific rules regarding home equity loans and cash-out refinancing (often referred to as "Texas Equity Section 50(a)(6)"), but these don’t prohibit homeowners from using funds for investment properties.

What they will offer you is an appliance package, or closing cost help, or a low fixed rate loan. 

Purchase price: $302,500 Cash invested: $5,000 Utilized VA Loan for a House Hack for my first Rental Property.

The modeling of this is actually pretty easy (see link: 42-unit proforma sample), but my model treats the pre-refi loan as I/O, but that can be updated based on your deal.

Give me a shout if you have questions, but here's the short of it.Best financing is going to be from a bank or a conventional construction loan.

You can allocate those proceeds any way you want - as equal down payments or buy one for cash and others with loans - It doesn't matter a bit as long as you use all of the cash and purchase at least as much as you sell. 

Another pro for a HELOC is not having to meet a HML's requirements for a loan (insurance, draw schedules etc....)

The LTV of the loans I’d conservatively gauge at about 35 percent.
