@Tony Zhang Have you tried doing a test inquiry? 

The major development in housing downtown for years was subsidized housing.My experience, and well as data that is readily available now is it is not good for surrounding neighborhoods.

I'm coming up with Total operating exp: $1557/moPositive Cashflow: $540/mo2% Test is at 1.8%Cash on Cash ROI: 20%Thoughts?

We have up until end of 2023 where we could sell the home and not pay capital gains (we meet the IRS' ownership and use test having it been our main home at least two of the past five years).

Hey BP,I am currently using TLO to skip trace my data. 

I need data from the past 30 years.

Hopefully these are accounted for or tested in the financials prior to the offer but it is rare for projected financials to show profitability decreasing over time as it is not what the investor wants to see.  

Another thing would be stress test the heck out of a possible refinance to see what that does to your ROI.  

I am researching property data collection and DM services to implement into my business for finding and contacting Multi-family property owners.

I was hoping there would be a perfect fit there but have not taken a bit of time to go through and look at them more closely yet.You would know more than me but seems like just using a free application or a very low monthly app can make the difference if you don’t have a PM for your properties but ya just test the waters with each one hopefully one works better for you and your personal preference.
