That's solid theoretically: the value of an asset is indeed the sum of its future cash flows, discounted down to the present.

But can my Real Agent help with me with other listing I see on Zillow and the other sites, even though the agent didn't present me the house ? 

Legally regarding rent here you would be required to waive late fees and defer rent  under the COVID legislation so I would do that.  

That is especially true for when all these mortgage deferment balloon payments come due in a few months.

Depreciation outside the retirement account just defers the tax until you sell it and then you pay the recapture tax and capital gains tax or 1031 it.

Or, one person st a time to go in with you present to search for a will or other paperwork.

Given the deferred maintenance, and current rent amounts I offered $750k, which also happens to fall in line with the area per unit average. 

Contemplating on an off market deal presented to me by my realtor.

I then need some help from a tax perspective ensuring I am using the correct forms and filling in the right info.I have taken $40k out of the profit and am trying to determine the most tax advantageous breakdown between deferred compensation and profit sharing, salary and dividends, employee and officer.

I sent them an email telling them that I cannot afford the rent reduction but I will waive late fees and will defer a portion of the rent and will work with them on payment plan for after all of this is over (same option I give my other tenants).
