House hack another property with a low down payment loan and use the remainder or the proceeds to either renovate or purchase another investment property?  

I'm currently renting and when  decided I wanted to focus on real estate investing, I decided not to buy in Tampa because of the low MF inventory and in home house hacking is not for me.

Buy quality properties in strong submarkets, finance with low leverage, bulk up on cash reserves, diversify geographically, and you'll be positioned to survive whatever the economy throws at you.

City-Data and Census.gov are solid resources, and sites like Rentometer can give you a good sense of rental prices.After that, I narrow it down to neighborhoods with strong fundamentals—good schools, low crime, and convenient amenities.

You’re in a great position with a property that’s appreciated significantly, a low-interest mortgage, and clear goals to boost cash flow and transition into full-time investing.

Assuming a 40% expense ratio, the net operating income at the current income level would be around $19,440 annually and $28,800 after renovations.At a $360,000 asking price, the cap rate based on current NOI would be 5.4%, which is low for a park with park-owned homes and required renovations.

Too many low income apartment buildings near by / vacant buildings. 

Is there a way to have No money Down or Low money down? 

Many realtors are not going to work in low value asset areas as those are generally rougher neighborhoods that are probably deemed to unsafe especially for a single women agent to be out there.

I don't work in Nashville area but $165 per sq ft seems quite low to me.In terms of financing, I would speak with a few construction lenders and also hard money lenders.
