Each REI investor will have definitely grown either in knowledge, experience, or current market situations since their last podcast.I view the BP Forum posters as the free/easy entry into BP product lines. 

Rentvine's claim is that they offer help getting set up with double entry accounting.  

Low entry costs How did you find this deal and how did you negotiate it?

Previous owners converted basement space into livable space (kitchen, shower, bathroom), but it does not comply with legal ADU unit standards (one separate entry, 6'10ft ceiling).

But appreciation in Detroit has been next to none over the last several years, and with entry level prices being under 100k it presents a real opportunity for investors!

This property offered less cash flow and a higher cost to entry than Harvest.

Should not be that much work even if having to do manual entry. 

It gets you entry into real estate investing and can be a viable path in an expensive market.

It’s a low-risk entry into real estate with built-in cash flow potential.

The median home price is also very low nationwide which creates a low barrier to entry.
