Have you ever broken that rule?

No upgrades.

That's to have a "Regional" section of the forum, broken up into NE, SE, SW, NW, MW sections, further broken down into states.

if they are good reliable tenants then don't fix what is not broken. 

In order of greater to least id prefer to replace these HVAC, ROOF/FLOORING, KITCHEN, SIDING, Electrical in that order with Electrical being the last thing I would want to upgrade or replace.

My farm can be broken into 25 lots at with a deep well and Fort Hall irrigation I imagine that if a person builds top quality homes you would stand to make millions, so just don’t look at Boise area for investing, not with what is happening in Bannock County. 

As other for mentioned you'll have a lot less of other problems: frozen pipes, snow removal, broken AC (in many cases housing doesn't have AC), etc..

If you want to give material upgrades away fine.

Orlando,I'm not too much more experienced than you but I bought in a park that doesn't sell to investors so I suspect that all rules can be broken or twisted.  

Recently I have broken off to a smaller company and want to introduce both myself and my company to the community.
