Here is a list of software that BiggerPockets recommends.

However, I am looking to augment my current income as a software sales rep (S.A.A.S).

So, i want to know what is the best option to analyze this case, because when i try to put this case in a valuation software the loan is discounted in the asking price and affect my cap rate and the IRR. 

Software that’s helped me personally:YNAB – zero based budgeting system and software; their philosophy will help you get out of debt and no longer live paycheck to paycheck Personal Capital – a high-level net worth tracking software PodcastsEpisode 108 - Grant Cardone...

-Interviewing/screening tenants (interviews, background checks) and managing property.From my RIA I learned there is software you can have your tenants submit their info to and it will run a background check. 

Software?

I would recommend utilizing the free landlord software out there that will perform market syndication for you.

I’m looking for the best skip trace software or company.
