Quote from @Jimmy Wellman: I've looked online for some information about the average % of the final home price vs. the price you purchase the home for and found that the home should be purchased for 70% of your home's final sale price. 

You can also buy a Landlord Forms package from Biggerpockets, me, or find one online and hope it's sufficient and legal.You don't need an app to manage your property.

I checked online regarding Elmsure.

Online Facebook groups can be fruitfulOnce you find a property things tend to move fast so have a good contractor available to help you estimate repairs. 

In a dream world - the comprehensive solution does all this: *task management and sequencing where you can drop a property into a sequence ie day 1 call, day 2 mailer (have it automatically mail out something like a postcard) day 3 etc etc etc*project management outside of the outreach sequences for what's next in the process ie schedule inspection, send the contract, etc etc*ability to have multiple users drive around and if you see a property you can tag an address and add it into a marketing sequence, and also track the streets you've hit so you're not wasting time driving by the same houses more than once *dialer (ability to parallel dial numerous numbers simultaneously to make cold calling more efficient - Ive used tools like orum and kixie in other industries, and when you receive a pickup, the other calls are dropped) *skip tracing/data provider *website landing page for converting online visitors to leads*electronic signature/docusign*secondary branded landing site on different URL for blasts for deal disposition to your buyer listWhat am I missing? 

You can also check their reviews online at Google, Facebook, or Yelp.

Are you focusing on online lead gen like Facebook ads, Zillow, or platforms like BiggerPockets?

Finding a random one online is going to be more hassle than it is worth.

I encourage you to take a look at out pages, reviews and feedback from other owners posted online.

I don't get into pissing matches online.
