Also adding value with improvements over time.

Now after not doing a single improvement on the home the ex wants half of the sale amount.There was no agreement in place when the house was purchased as to what would happen when it would be sold.Legally how would this be approached.

So, as long as you do things that make sense and stick to it investments will improve with time.

What would the IRS consider improvements that must be depreciated? 

In terms of improving targeting, I have heard that you can purchase something akin to a title search here in Ontario through MPAC (or maybe your local municipality) that at least gives you the names of current owners but each search costs about $8 so you don't want to do many of those!

A CPA would know whether or not you could take bonus depreciation on the capitalized improvements, but since you already know what the cost was, there is no need for a cost segregation.

This is due to bonus depreciation which allows taxpayers to deduct 100% of qualifying property costs in the first year, in addition to regular depreciation for new construction and improvement.

Almost all of my owners have complied, and it has improved the maintenance request area and vendor relationships consistently.

have any improvements been made?

We might see a little improvement in Greenfield with the Amazon warehouse extension!
