For example, in Louisiana the Dept of Rev, which reviews each project’s qualified expenditures, has a specific form they issue to the applicant as final credit amount

This last category represents Capital Expenditures (CapX) which are written off over time.

I want to focus this discussion once I have completed the renovation what the useful lives I will be able to use on the different expenditures I have during the renovation.

Capital expenditures ?

What you are talking about are expenses that are incurred between tenants or during tenancy - essentially, after the property is placed in service.For expenditures that are incurred before the property is placed in service, almost everything needs to be capitalized. 

Also, any real deal will surely require incidental expenditures such as paying for inspections, some form of marketing budget, etc.For those of you who have actually done this, how did you get the deal?

and remember to ask your tax accountant about loss carry-forward to see if you can use those expenditures to offset future income.

This of course is dependent on the mortgage balance being at or below the new market value, and that you can improve the NOI with minimal capital expenditure.

Build in routine maintenance, capital expenditures (based on current life, expected replacement costs),  potential vacancy, management costs ,any other expenses.I think asking someone about their monthly cash flow is totally misleading if you are missing all the calculations.After buying 11 out of state properties in 5 states

So once again, do I continue to invest in solar to minimize monthly outgoing expenditures?
