I've downloaded the DealMachine app and wanted to get some feedback reviews about the app.

If my kitty was fat enough, I'd take 5% any day and throw my laptop and iPhone in the trash, sleep till 10am and play guitar with my amigo's haha

@Edward Lui management is free I use my iPhone.

Zillow's API is no longer offered (or they make it extremely hard to access these days - have had no luck finding an updated link/page for it), Redfin has broad-stroke CSVs you can download that only give 5-10 fields of info and not often at the metro area, you can't legally create a tool to crawl these websites...I'm looking for 1 (or a handful of sources) to pull together basic metrics at the metro/city level for US real estate.

@Mohit Arora recommend you spend more time studying TX landlord-tenant statutes.Your lease is probably pretty basic as it didn't really cover this issue - and it probably doesn't really cover a whole lot more.Google & download as many TX leases you can find to copy & paste to improve yours.

Our version is available even now for download on our old Towne Square HOA account, (mgmt thru 2020, I think). 

I think you should take a week or 2 Bob and write a "Crash Course How-To" e-book and then offer it up for $10 per download.

It will auto download all your banking and credit card transactions.

By the way, I downloaded the kindle version of the book you recommended and I plan to start reading it tonight.Thank you again for the question you asked and the interest you have taken.
