@Tiffany Da Silva, I use quickbooks online for bookkeeping and I use a "Profit First" approach to managing cash.

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.

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. 

I’d have a better picture by sitting down with someone at a bank, but I did a calculation online and the new loan on cashing out $130k would still be covered by the current rental payment.

Do you have any tips how you obtained the phone numbers online from the MF property list you got from Listsource?

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?
