As far as calculating cashflow, I would still suggest considering all the PITI and other overhead expenses.

.: Stessa isn't good for keeping track of tax deduction items.Stessa was designed to just look at P&L.

I use QBO to keep track of my properties and do this for my bookkeeping clients also.

For another business I run I do post daily accountability in a FB/mentorship group and that does help me stay on track.

figuring that if I track and work towards creating and "presenting" 250 specific deals to my clients.My Theory being: Tracking "deals presented" will pull forward the need to go search and find deals, and will also drive the deals closed and revenue numbers, so we shall see but logics out to me so I'm liking it so far.

Quote from @Dinesh Nair: I am a Canadian investor with a US corporate entity- we closed on our first property and now working to find financing through a lender… however rates keep changing all the time.. is there a site to track rates ? 

I see 3-5 as a fad.Fractional ownership - way to much overhead for these to be profitable. think "timeshare".STR in non traditional markets - running a STR is a business and real estate, boils down to location location location - who would want to go to a conference and stay in a STR vs. the hotel where the conference is at, most businesses pay for this I do not see why.Mixed use with green - this has been going on for years- it will continue but it is also more expensive to build - which means higher costs to use.Not trying to be debbie downer, I have seen these attempted to be done in the past and they really have not been successful.I do really like the BTR model though as I continue to see that as a very good option in the future. 

Others recommend tools like Stessa or Buildium to track actual costs and project future expenses. 

All you need is a single place to track tenant information, payment history, maintenance, and other things.

Long term goals in mind that I need a track record and capital for!
