I don't think your wood planks or bead board are going to look good and I'm not sure its going to be as easy as you think to go over the popcorn, as the surface isn't going to be smooth.

Otherwise you're presumably talking about adding square footage, in which case you can get a ballpark estimate by thinking about how many square feet you would be adding and multiplying that by the cost per square foot for construction in your area (which can vary dramatically but you can get a sense of the range from Googling and looking at pages like this).

Some expenses/deductions can be added back into the Net to hep but if you claim any "un-reimbursed" business expenses that’s a total loss and cannot be added back into the Net.If a person is overseas or out of the US working and does not claim US income/taxes it cannot be used.

After dealing with the issues these tenants have caused me, I will be adding a lot to my contract. 

Any/all depreciation should be "added back," thus a non-issue.

We also consult with out-of-state buyers on MTRs/STRs, so "consulting" needed to be added as a coverage area.Anyway, I wish you luck!

When it comes to Cerner and what types of jobs they will be adding I would be able to assist more than anyone else on this page.

Let me know if You want to be added to the list 🙂

A good solution would be adding yourself as a service pro, and if you don't want certain invoices to be visible to the tenants, assign them to a service professional. 

IF you had a separate company to service the loan, those service fees you actually paid to your own company would be added to your basis.
