Use Quickbooks or Quicken, or some other accounting software that can present your information professionally. 

Reading about "web scraping software" and all those excel spreadsheets has definitely been fair warning: this is serious business.

I personally will never use turbo tax or any software like that again because at the end of the a really good CPA will be able to help you save money or structure your taxes the way you want them. 

I currently own 10 rental properties and am looking for a property management software that I can grow with. 

Which software have you found the most beneficial?

I'm kind of debt averse, especially since I will already have two mortgages.I am planning to go with a rental management company so I don't have to deal with the hassle of managing it since I am a full-time software engineer.

Not sure about the most practical approach on your side of the line, but when we started our real estate {ad}venture, we took a chunk of retained earnings from our software company and funded a separate entity for real estate.   

LOL  It has also lead to me learning the pure shear value of open source, especially when it comes to landlord software.

I am not handy at all (software engineer: great at building software suck at anything physical) so I think I should probably utilize a rental management company.Thanks again for your kindness and patience with a rookie just trying to soak up any of your knowledge I can to become a seasoned vet in a few years!

Thought I would  have time to network to find a document solution, either real estate attorney or software or both, but a deal landed on my desk yesterday that I really want to do, but must be able to close in two weeks.
