Just as a reminder in addition to the interest rate, amortization schedule and fixed period of the loan, inquire about: 1) Prepayment Penalties (In case you want to refinance in a few years), 2) Possibility of Rehab Funding, 3) Reserve Requirements, 4) Personal Guarantees, 4) Rate Adjustments (i.e. at the 5 year mark) to understand other variables in the loan product that works best for your project.

@Joseph Lombard The HELOC is best described as personal short term financing.

I have to do a little more due diligence before I feel comfortable with sending them any of my personal info.

I have good personal credit (~730-740), average-high personal debt (mortgage, student loans, vehicles,) and I am employed making $90k/year.

If you can't keep control of your personal finances, you are highly unlikely to succeed in real estate investing.

In order to undertake a new build I would have to personally know the builder and be comfortable with his work.

If you have cash, know that 99% of wholesalers will have low repair values and high ARVs that don't match the actual data or upkeep of the house.Also, ask if this is being daisy-chained, meaning are there other wholesalers or investors in the line between the person offering you the deal and the seller.

I personally would approach this with a self assessment.

This is why a machine cannot calculate for the irrationality of a person buying a house over value because they like the cute garden. 

like - your own market. or a market a couple hours away that you can spend some time in person in. or where you went to college. or where you like to vacation.
