I've researched property data aggregation and skip tracing sites, but am moreso focused on finding cash buyers/investors.

We subscribe to a market research platform called Yardi which only provides information on multifamily properties 50 units and larger so if you are invested in a property that is 50 units or more, I would happy to provide quick "back of the napkin" valuation and methodology.

Looking to get feedback on the best cloud service you are using to store the data like contacts, photos etc.

Use data and analysis to prove your ideas that it's a good investment.

For others like my clients I collect the data, find the deals, do the analysis, and provide references to get the property stabilized.

We made the best guess with the data we had, reduced that a little, and ensured we beefed up our emergency fund in case we're wrong.

Why don't you use a bit different model where your potential clients can pay perhaps $250 (or a bit more if reasonable but no more than $500) for an hour meeting to talk to a real CPA who has been trained by you and determine whether or not they can save me money on taxes such as capital gains or ordinary income or passive income by forming structures that makes sense for using up various deductions and write-offs to the fullest extent to off-set the various sources of income and let them show me how they can eliminate my taxes down to minimal to zero in that quick session, it is like a preview session to what is possible given my actual data. 

Where were you buying your skip trace data before?    

The product is FICO score-driven. 

It's hard to give the best response without seeing the data and the market you're in for ourselves.Good luck either way.
