(and certainly not all the extra interest that accrued at the higher default interest rate. )Question : Do we, as investors, then get to claim a tax deduction or write-off for all the interest - including the default interest - that was not paid?

I haven't tried it so it's a bit of idle curiosity for me at the moment.   

Since the lien was purchased, more taxes had accrued and another 40 to 50K in new taxes was due. 

GET IT DONE RIGHT the first time.Out of curiosity, where is your unit?

Just go in and ask to see it to satisfy your curiosity.

Remind them regularly of the unpaid amount and the accruing late fees, interest (per your agreement), and the potential for more significant action ie eviction.Late rent will happen but do what you can to prevent it and don't let them slide. 

@Antonia (Toni) Foster It's really more curiosity than anything, why is the move in fee more advantageous for you in that area?

The second is for HUD since HUD is insuring that the homeowner.When a person takes out a reverse mortgage, they will get a loan that includes the appraised amount, accrued interest, mortgage insurance, and fees.

Out of curiosity, has Pasadena made any more progress in turning itself around?

That tax bill will still have to be paid in full, even if you buy the property at a great price from the heirs, the back taxes plus the accrued legal costs and interest will still have to be paid.
