I'm sure this isn't common, but I had my first deal under contract within 48 hours of becoming aware of the fact that normal everyday people can invest in real estate.On a Tuesday night, my friend mentioned that he owned a duplex and said "I sometimes forget I own a rental property until I receive a check at the beginning of the month."

As far as I can tell there is are no documents for the back house.

If investors are still holding their interest in the fund on Dec. 31, 2026 then, regardless of if they continue to hold the interest in the fund, they are required to recognize and pay taxes on the deferred gain on that day, subject to any increases in basis they may have received for holding the property for five years or more.

He also stated you would receive the leads around week 3 and proceeded to get rather snippy with me because he evidently said this on the webinar.

If the landlord gave you documents (including the estoppel) than you may be able to do something if this what you find when you officially start collecting.  

This looks like it can qualify for section 121 unforeseen circumstances that  IRS recognizes.I am sure all this is documented and you will have easy time defending it as well. 

I purchased a tax certificate that has matured (3 yrs) and I now will be receiving a tax deed.

Finally received a text from tenant telling me I can terminate the lease and yet, no rent.

Also, how long do you have to live in the multi family unit so you can receive the loan?

The lessee is responsible to the lessor for any rent that the lessor did not receive.
