No house is going to be perfect and some things are an easy fix.  

TLDR: Quicken (quickbook’s little brother) is super easy, cheap, and still overkill for someone with less than 20 properties.

And easy for us to fulfill 1031 exchanges now. 

I'm doing this exact thing right now- I've been pleasantly surprised by how many people in my network have resources, cash and interest in something like this. 

Each corporation runs differently so some are easy to deal with and some not so much.

I think it helps flippers as it is easy to find the purchase pricesp versus selling price.  

I use Baselane because it makes having multiple accounts super easy.

It has surprised us delivering nearly $60k in gross revenue annually.

I've been surprised at properties that have passed conventional financing though...and even FHA....also, one could present 2 offers to seller--one for a cash offer and one for seller financing (at a higher price of course). 

The payments are super easy!
