The help I have provided with a few home remodels has consisted of kitchen and bathroom layouts, flow and functionality, fixtures and finishes of the home, all while trying to stay within budget.  

They're all very similar in my opinion, and do about 90% similar functions.

Both screen doors upstairs do not function correctly.Plumbing problems-The garbage disposal in the kitchen was not cleaned, is smelly and the rubber is flipped outwards.The bathroom sink in the smaller bedroom does not drain correctly despite us using an entire bottle of drain cleaner on it.Common areas that are not kept clean or have garbage-There was no attempt to clear the patio of years of accumulated debris and filth.

Quote from @Zachary Deal: One thing to keep in mind if you are doing this is that you are likely to create "functional obsolescence" which could mean you are not able to get a new loan against your property and it can be difficult to resell as well. 

For the most Service has been responsive, they're adding more functionality, though wish I could track maintenance/repair requests and service fees for rent, but the cash management is what's keeping me here for now.

But he chose that one over the others because it was very user friendly (for our older managers) and it offered a 'Groups' function where we could add certain individuals to different projects.

They do everything for you (payments, taxes, insurance coverage) - the website and app are easy and functional and you can vet your guests!

After investing $47,000 in thoughtful renovations, we transformed the property, enhancing both its functionality and appeal.

To justify the land cost (if I recall), you needed an already functioning property in the land and needed to add the Tiny home. 

My suggestion is to build a spreadsheet and include the net cash flow to you for every month of the deal, then use the IRR function to figure out your return.
