I concur with Steve however I have never owned properties there.

Once you highlight a couple of locations, pay attention to active inventory in the areas by going to listing sites and checking out properties for sale.

I already have one rental property that I own, but want my goal is to reach 40 doors in the next 20 years.

On top of that you have operational inefficiencies that local investors simply don't have.Some of the absentee (OOS) slumlords are giving all of us property owners a bad rep here in Milwaukee.

I'm currently under contract on a rooming house property in Bergen County. 

Amongst the common misconceptions I see by posters on BP are that hard money loans are junior mortgages to fill the gap between institutional financing and down payment; that it is in lieu of down payment so the borrower can acquire a property with “no money down”, and that it is money borrowed to use for an earnest money deposit.

Your suggestion if I understand correctly after googling the terms, is too look into county owned properties or lots?

We now hold it as a rental property that cashflows well with a 2.75% interest rate (got lucky with the rate environment at the time of purchase!)

Welcome Tom,This is the area I have my properties too.

Me and my husband would like to purchase a property - single family house 3 -4 bedrooms to do airbnb in San Antonio, Texas.
