But that also complicate things as you wouldn't be able to get a conventional loan.It seems like you'll be investing long-distance.If you haven't read "Long-Distance Real Estate Investing" by David Greene, I would highly recommend it.

I'd rather spend 300 a month on a subscription + texts on batchskiptracing and actually know when my stuff goes out vs 75 a month on a subscription and texts on this software and have no idea when all my texts are going out, not being able to stop a campaign unless I delete it, and just praying that the complicated steps I took when setting up my campaign don't backfire, or crash, or nothing goes out, or whatever.

Normally not that complicated.
