Well I have leaned a little more about 1033 Exchanges and would like to pass along to the BP group.
I have found the IRS 1033 (a)(2)(A) form to send with your tax return. At least I have found the Turbo Tax form to do this.
It does not have an official IRS form number so ... Anyway the first tax report filing after your fire loss you fill out this form and tell the IRS the details what and when it all happened and how much you received in insurance and sale of the remains.
You also list how much the property cost and when you bought it. If it was a 1031 property to start, you provide the basis which includes the original 1031 reduction as well as the normal allowed year to year reduction claimed on your tax returns since renting it. If you have not yet replaced the property, you state on this form that you are reporting a delayed 1033 Exchange and describe your intent to replace it with a "like kind" property within 2 years.
"Like kind" is a bit more restrictive than the 1031 rules as I understand for rental property it is residential for residential and commercial for commercial and the two can not be mixed. I assume SFR to Multi family residential is OK.
As I understand the 2 year period, it starts with the first tax return notification. So a fire in 2020 starts in 2021 and the replacement must be reported by the 2023 tax return. I don't plan to test that definition too much and plan to replace by two year from the Fire loss just to be sure.
There is no call for a QI which is good because insurance payments and mortgage payments alone is sufficient nightmare.
There doesn't seem to be any requirement for mortgage matching like the 1031.
The only issue is the Replacement property must be same or greater than the loss property gross cash obtained.
As a side, in such cases insurance checks are written to the insured AND the mortgage holder. Unless the insurance is sufficient to pay off the mortgage or even if it is, don't expect to be able to sell the remains very quickly.
Mortgage companies are set up for conventional closing where they get all their money from the escrow or lawyer'c closing.
If people pay off their mortgage with out selling, the system eventually produces a letter to be recorded at your county deed office that the deed to secure debt has been satisfied. The mortgage company can't you or your lawyer a simple note that the mortgage has been paid. Totally unthinkable that anyone should nee this to sell the remains of the home!
For checks coming in from insurance companies they expect to hold the check and payoff small amounts to a contractor as the home is refurbished. These three processes are totally different departments and there is no hope in changing the systems!
So I hope y'all never need to do a 1033 but should you have the misfortune to need to, it seems like a nice silver lining tax law. Again Thanks to @Dave Foster for pointing this out to me.
