In most of Southern NH when you're dealing with duplexes or smaller multifamily properties, the numbers produce low cash flow, break even cash flow, or even negative cash flow (as is the case with most duplexes). 

There's no debt and they're producing income, so I would recommend keeping them.

GOAL: I want to purchase another income producing property in about 6-14 months from now (depends on market and my energy).I don't have a downpayment. 

Single family homes in Tampa have almost never produced positive Cash Flow from rents.

I like investing in Oklahoma since it generally produces good cash flows.

But I have a suspicion that your property is probably under producing where you could be (even if you didn't increase your debt any).

Then research and find a market that will produce the results you want.

You just need to make sure the investment you buy can cover the costs you will be incurring and produce cash flow for you!

Then, he used the funds from the biz to buy income-producing assets.

I already have multiple real estate businesses that are producing income, and have my mortgage loan originator license so I will obviously be doing an internship with a company within the real estate industry, and it may just be a company that is already a partner of mine.
