This will eliminate most of the lower end properties and neighborhoods.I hope that helps.

I recommend signing leases in person though, as tenants are more likely to ask you questions that will help eliminate issues in the future.

Certainly, combining the tool of using sec 121 to sell your primary residence and 1031 exchanges to sell and increase your rental portfolio will eliminate and completely defer all tax on profit from sales.  

I'd suggest that there is "space" to drop the rents to get better quality candidates and eliminate turn-overs.

Eliminating tax enhances your roi quite a bit and you really haven't stretched yourself too much philosophically or financially to do so.  3. 

The tenant paying the mortgage reduces your negative cash flow, but doesn't eliminate it.Any equity built up is very small in the first 5 years, and has no usable value unless you sell the house or refi to tap into it. 

Bad Property Management: This is the hardest risk to eliminate by due diligence.

When my wife and I reviewed this release we thought that our 3x income and 600 credit score requirements would eliminate the section 8 tenants. 

Say the rehab quality, neighborhood, and property management all check out to lower (but not eliminate) some of the risks for vacancy and maintenance.

@Westin Hudnall If you 9 investment properties in addition to your family home and you are only 30,  I think the way to go is to simply use the HELOC to eliminate your mortgage.
