I hired a licensed Colorado surveying company to complete two Improvement Survey Plats two separate, adjacent fourplex's located in Evergreen CO.

You can offer a longer term lease, offer to make improvements to the property etc in exchange for flexibility in the lease terms to allow you to sublease.

Those batteries are not cheap and have short life-spans.

Some people perform value add improvements to increase rent and cash flow. 

Only the improvements that can be depreciated in 15 years or under can qualify to be accelerated to be taken in the first year, so long as I meet a long list of other requirements.  

If you knock out a lot of improvements when you first buy the house, it can be applied towards your taxes (consult your CPA blah blah blah).

So your depreciation each year would be 1/27.5 of 3/4 of the improvement only (property value - land value).

If you don't own the property and want to sell it for someone else, that is where you are acting as a real estate agent and would need a license.So, wholesale is where you purchase a property, then resell it quickly for a "slight" mark-up without doing anything to improve the property. 

What funding method besides traditional mortgage makes since when buying a rental that needs improvement but there are no comps and the values haven’t been increasing much.

I also will invest that little bit of extra cash in improving the property since it does need some updating.
