You may want to do some direct mailing to non-owner occupied duplex owners - these are usually the best deals because they cut out the middle man.

I personally am huge with Freedom to Choose-https://freedomtochooseproject.org/We go into California prisons and work directly with the inmates, teaching them spiritual psychology principles that help them see their own worth, help with forgiveness, anger management, making them generally happier, etc.

My current house 3 blocks away in one direction is $350-400k house, and the other direction are $50-75k condos/apartments.

Hi, I was wondering what the best way to find the labor and material costs for a specific area.

Direct message me if you need further details.

What is the best, cheapest, easiest direct mailing list company to use?

Saved $600 in 3 hrs cleaning and tightening up 4 dead or smoking wall heaters instead of replacing, and that didn't include install labor... could go on.

Jeff,If you have Checkbook IRA, that means that you have a custodial self-directed IRA which made investment into single member LLC of which you are the manager and your IRA is the member. 

Can anyone recommend an easy to use online payment app or method for allowing tenants to pay online and direct to my account?

Awesome job @Michael Noto Thank you for bringing us along for the ride to see costs and labor!
