@Thomas Q.If you don’t mind, let me give you my point of view from a smaller scale investor.

I’d throw that theory out because you are not really looking for resource to scale a business from.

Manufactured housing is personal property, not real property or 'Real Estate'. 

And selling in that 700-900 range properties tend to sit a bit longer because there are less buyers in that price range.I have also considered building a spec home at a considerably lower price, and I am also toying with the idea of putting a manufactured home on it for around 100k and getting a quick return. 

Now that I am larger scale and corporate, I use QBO (Quick Books Online).

This will be helpful as I attempt to scale my business interests in this market and others.

I did forget to mention I do work full time as an operations manager for a large manufacturing company.

I also knew I wanted to learn as much as possible about renovating and scaling my business as well. 

With multi family you have economies of scale the larger the property and the more units you have The more income you will generate to spread out the cost and reserves

Sorry that is one of our best kept secrets (they are not big enough to handle more and not really looking to scale).
