Sorry I could keep going as this is What I Have do for 30 years This is My current field of work.With out seeing the property or knowing all Linear feet of all materials and depth of utilities and soil conditions, equipment and personnel, import/Export, Subs, just to spit ball a price is not possible.there are so many more things that are involved with what your asking for.  

Both programs allow you to export all your data so that you can forward to your accountant.

I would love to see BP add an excel export feature to the rental calculator.

LOLThe American middle class was stronger when we exported or created more the we imported or consumed, Mr economic genius.  

The Teak for example will not be sold in country which is poor, but exported to India and China.Teak costs about $USD 2.00 for the plant and to plant. 

You can also track expenses through these platforms and export them, so if you don't want to deal with a spreadsheet, that is an option too.

Typically I can export the transactions per month into Excel and it's not more than 30-40 rows.  

Listsource is another one but I like how you get 10,000 exports per month with propstream.

You can filter by the beds and baths and other aspects to make the results as close as possible to the one you're comparing.When I build my semi-automated hotsheet for investors, I take exports from the MLS from both the sales side and the rentals side, pull them into a SQL Server database, do some data cleaning to screen out as much of the garbage as possible, and run what I call my "magic query" that joins sale listing locations to rental listing locations by a conditional match on subdivision and beds/baths, or the average of the entire MLS if the subdivision is given as "METES & BOUNDS", with a flag in the output showing that those M 'n B rental numbers are MLS-wide averages for a given beds/baths and will need a more in-depth evaluation (like rentometer) if the estimated cash on cash return for a classic 20% down scenario, looks promising. 

Try going on a "break" with that realtor and look specifically for one who not only understands investments but who also has good technical acumen for exporting and doing deep analytics on the MLS data.
