@Sandeep Dhall we are releasing a v2 of our list builder in the next month that will offer many more advanced filters in the list builder and a new look so you can search by individual properties and run comps.For MLS - yes, you are going to find data here that is not 100% accurate.

Renting out property for 2600 a month, and landlord making 600 cashflow.

Hi, I am looking to invest Single Fam or Multi Fam Resi, potentially in the Dallas market in the next 4-6 months.

Maybe 6-8 months ago, I would have answered like Don, but I spent a day with an investor in one of my solar farm projects and I was absolutely floored. 

Expenses: Mortgage: $3655.55,Property management: $470, Water: roughly 100/month.

We've raised over $3M in the last 9 months, and zero dollars before that :)

I would now cash flow $1,238 a month on this duplex.

That mortgage is servived through one company, and this one is serviced through another.

The problem I have with your assumptions is you are suggesting he buys a $400,000 property and gets $3,000 per month rents.  

Deduct your late fees from the amount paid the following month.
