@Jim Edelsonyea, that's the same guidance we had -- and I was actually happy to comply because it's essential to us that it works 100.000%.

I'm happy to provide them with my SSN for tax purposes to comply with the new IRS rules, but there seems to be a problem with Apartments.com's system.

They want us to fix all this and mold remediation and haven’t even paid rent for this year and now we have started to evict an will be filing today but the city has deadlines and we need to comply. 

In my tenant screening interview I ask:Has a landlord ever given you a notice to comply with the terms of a rental agreement?

Failure to comply with the process described was, by statute, considered an Unfair trade Practice (UTP).

I would comply with estate tax obligations if necessary.

Failure to comply allows the tenant to have the landlord use the security deposit towards the rent......this includes failure to just send the letter.

Comply with what the IRS stipulates there, and the gains on your residence below the threshold  are excluded from capital gains tax. 

But why do 1031 exchange at all - if I want to cash out eventually.Repeated exchanges would take a lot of time to identify properties, hold them with tenants, pay closing costs, and do a lot of other things to comply with the regulations.Trying to understand what is the motivation of doing 1031 exchanges - if one has to pay taxes on all the accumulated gains and depreciation recapture eventually anyway.21 is 21 - and even three times 7 are also 21.

You do not know if it complies with state laws etc. and if there ever is a dispute and it did not comply with the laws of the state not only could you have the lien wiped buy also face stiff penalties.
