I hope that the information on the site is helpful to you, as I have no knowledge of your market or how it functions.

As a property manager myself that is one of the main functions of our job.

It has some functionality in producing plans and elevations, but doesn't come close to revit or CAD. 

Use the search function on here, you will find a ton of info about how to get started.

Hopefully its appraisal is not JUST a function of average rents.I reckon its main attraction is that it HAS had $25k spent on it, but which has likely raised its appraised value by less than that, say $10k.

It wasn't even a particularly cold winter (in southern MI) but it just depends on the conditions, how the wind blows, etc- you never know which year is going to cause a problem.I'd consider having someone turn the system on in the spring also- it is a good time to check that all the heads are popping up and aimed properly and functioning, the freezing and thawing of the ground can make them move.

It is very functional and intuitive so far.

Assuming he is a below 5% owner and does not participate in any function of the real estate within the partnership.

@Bryan Creed A lot of the things on this list could have been tested and verified as functional during a quick sweep of the home before the tenant moved in.

These industries have little overhead in terms of capital expenses, so they can expand supply of their "products" without inflating prices.It's the manufacturing and durable goods creators who need to make step-function investments into factories, equipment and inventory to keep up with hyper-demand, and it's in these sectors that we tend to see the most inflation.In fact, in a purely service-based economy, there would be much lower inflation overall.
