Water goes wherever it wants. 

-RobHey Rob,Sorry to kind of pour cold water on your idea, but I think you would be better off NOT getting your real estate license at first and use a realtor as a resource.

One good idea is to buy the $10 leak alert detectors that will scream like a fire alarm when they are in contact with water.

Still have to save for roof, appliances, hot water heater, hvac, exterior paint or siding, etc.  

The MHP is on city sewer and water (which I believe to be a bonus). 

That might not be the warm and fuzzy answer you're looking for but you do have to understand the loss of the business owner and liability of vacancy that they're bearing because of your absence.

Hello Austen,Thank you for the warm welcome.  

These buildings will have shared community gardening and parking.I'd like to find an attorney that can help with setting up the HOA & bylaws.The units are all set up as separate entities (separate solar systems, etc...).Yet, there is actually quite a bit to think about in terms of maintenance & other hoa rules.How is the watering of the shared gardening space being handled?

One of the largest cost is going to be in bringing the lines (gas/electric/plumbing) over and of course the drains for the waste water. 

I put solar panels and a tankless water heater to minimize utilities since they are not truly split.
