I am an accountant by trade so I love QB, but I'm at 147 units now and I need something that can help manage the non-accounting side of my business.

There is a lot of information we have to learn, from money options to negotiating skills to land lording and property management skills. 

I'm military myself and can tell you first hand that under pressure (like a life threatening situation where you would use your weapon) you will lose fine motor skills and the ability to think with absolute clarity.

Or you could leverage your residential skills buying smaller multi-families.

If the latter is true, I suggest that you start working with distressed property owners and drill down the reasons that motivate people to trade equity at a discount in return for something that can or will do that others won't. 

In everything I've ever done knowledge and networking can cover a lot of hard skill deficits. 

My objective is to create a solid business moving Charlotte’s worst properties from the hands of owners who don’t have the ability or desire to renovate and maintain them into the hands of skilled investors and landlords who will create attractive, affordable housing for area residents.

Small parks are relatively illiquid and do not appeal to larger buyers, so they trade at high cap rates (15%+).But you have a hundred+ hours of learning to do.  

Plus my own time-management skills are unparalleled and therefore have time needed to do stuff.

Personally, I am willing to trade cap rate for equity, meaning I would rather own the asset and have a lower cap rate than have no equity but a higher return (which is lending).
