I would not invest in states like New Mexico that have a gross receipts tax. 

The MLS / Zillow listings tend to not have a lot of detail, for example type of heating and cooling is often vague, whether there's existing tenants isn't often stated (although if MLS has a "gross monthly rent" figure I'm assuming it is), and there's often only pictures from one of the two units so it's hard to tell what shape both units are in, or what their layouts, features, and amenities are.So that I'm not sending my agent to view every duplex in town (especially because I'd imagine the listing agent would have to find a time that both tenants agreed to), is there a way to more quickly weed in or out all these faceless duplexes?

So, in addition to the good tips others shared, advertise on your car and your friends/employees' cars?

Our currently yearly gross cash flow totals are(once this current property is finished with the renovation and rented out): $43,000.00-ish depending on some laundry income.  

I assume there are no employees so no Employment Taxes will need to be filed quarterly.  

Wells fargo froze my accounts because i mentioned to a branch employee that i did not recognize a small ( $7 ) charge .

@Richard Raghoo - to increase cash flow, you only have two options: raise the gross income, or decrease expenses.If you are set on sticking to residential, you will have to find creative ways to decrease expenses.

I self-managed my apts for years but it's time to hire a property manager (as a w2 employee).

We also improved the house with custom closets, landscaping, curtain rods, additional cabinets, fencing the back yard...We also lived below our means so we could buy stocks.We participated in an employee discount stock purchase plan.  

So there are 19 empty space pads. 5 out of the 6 apartments are rented.The total gross income is $4,600.00 a month.If I Rent the remaining three mobiles and apartment.
