I am specifically interested in single family and small scale multi-family homes (duplexes, tri, quad).  

One of the reasons to make it the first is that it is convenient for a tenant who moved in on say the 25th or 26th to start paying on the first and 5 or 6 years later they think they can move out on the 31st without extra charge so its better to pro-rate up front.I only have a few so keeping track isn’t that bad but I could see how this would become a pain as I scale.   

IMHO, it’s blown way out of scale.

Are you talking about wework for local developers on a smaller scale?

You might be able to order one from the manufacturer to replace the stripped one.

., count your blessings, at least she is supportive, this could be way worse and I have a feeling if you keep trying to change a grown person, it just may get to the worse side of the scale.

By doing this, you can scale your business much faster than if you put more capital in up front, then have to save for your next acquisition. 

To scale though, you would repeat the process until you have the number of properties that yield the results you want in your portfolio. 

As far as comps go, it would effectively be the same as analyzing all the properties in the town plus the scale effect of controlling all those pieces (i.e. how would that benefit or hurt the owner to own everything in a small market?)

Three of the acres have a manufactured home with tenants.
