We set a policy that all of our communication goes through our property management software outside of normal business hours.

Now that I'm doing it full time, the need to be more organized with costs, contractor and materials scheduling etc. has become apparent.What software are you using to project manage your rehabs/flips?

Each vendor schedule everything with the tenants, no keys required.You should checkout Appfolio, they offer a call center for $200, plus with their software you can manage the portfolio more easily yourself or hire your own manager to do it for you at some point, etc.

I feel it is so important, I designed software to analyze, plan and execute it.  

Does anyone know or have used Daniil Kleyman's "RehabValuator" program?
If so what are your thoughts on this?
It's pricing @ $29/month or $197/year.

Set all your tenants up with autodebit software and make that a condition of the lease.

Do you have any software that you recommend that I use?

I actually bid up the price between myself and the auto bid software to what I felt was the rock bottom lowest they would accept, and they did!

I am looking for retirement software that you can add your real estate portfolio to.What are you using and why?

I do not have any experience in the real estate industry(software engineer by trade), but I'm willing to put in the leg work to learn what works and what doesn't.
