vary down payment; ltv; and expected purchase price. 

google lolDebt service coverage ratio (DSCR): The DSCR is a financial metric that compares the property's net operating income (NOI) to the loan payments.

There are some areas outside of those few towns you mentioned, Portsmouth, Durham and Salem, where you will need quite a bit less for a down payment to get started, but they might not be areas that are super desirable for you to live. 

Don’t make car/house payments or utilities.

I'm prepared to make a down payment of around $70,000, and without factoring in rental income, I can qualify for properties priced between $650,000 and $700,000.

You may be able to go up to 70% CLTV and qualify based on the market, short term, or lease rents covering both the first mortgage and second mortgage payment.
