For instance, if there was a total of $250K of debt on those properties that woud leave you with $350K of proceeds to use to purchase $600K of real estate.  

Quote from @Brian Malavsky: Totally agree with everyone else and I didn’t see anyone mention an “Umbrella Policy” I just got quoted this week for $1,000,000 coverage for only $350/yr.

The plan is to pay the debt down (it is due at the end of the year), pay back vendors (I forgot about this on my last post.

My CPA also quoted $350 to send out only 6 1099's total in 2 LLC's.

I'm thinking interest rates will sit at 6.25-7.5%, with total cost at roughly 210k.

Doing a 100+ unit deal is totally doable as your first transaction.  

I'm totally sold on it.   

We signed P&S agreements on 6 different properties totaling 20 units approximately 8 months ago and received a call today that the price we thought we were buying at has to-be increased on average 13% due to the increased cost of construction.

Of course, I totally understand that you wouldn't want to do if that guide is written by another real estate agency, in which case you have option 2.b.

Other software also has bank feed integration, automated income tracking, receipt scanner, accountant-approved reporting, etc.Of course, it totally depends on what features you prioritize!
