I had saved this thread for a reason - and after a lengthy conversation with counsel today, felt it necessary to correct or clarify the prior responses with respect to (i) leasing while in default, and (ii) the PTAF Act.
First off, it is NOT fraud nor is it illegal for the owner of a property to have an existing lease while in default since the owner still OWNS the property and technically can cure the default anytime up until the title or ownership changes hands. There is, in fact, state law (NV) that protects the owner of record and upholds the lease and the owner can evict the tenant for breach of the lease/failure to continue to pay rent. Now, if the owner leases the property subsequent to a Notice of Default, then some states (i.e., NV) require that the tenant be disclosed in writing of the NOD. Again, the lease is upheld and perfectly legal, so long as the disclosure is made. An "assignment of rents" clause is sometimes included in the lender's note or separate document which gives the right to the lender to collect rent in the event of a default, but like the obscure due on sale clause, is rarely enforced.
Much to my surprise, the PTAF Act specifies that the lease be "entered into before the notice of foreclosure to occupy the premises" in order for it to be held valid in the context of the Act.
According to counsel, a "notice of foreclosure to occupy the premises" is clearly not the same as a NOD or "foreclosure notice", therefore, a lease entered into after the NOD is filed but before a foreclosure eviction notice, would be upheld under PTAF. I brought up the fact that this definition ambiguity is probably not yet supported by any case law given the the act is so new and hasn't been litigated enough for us to really know. Thus, the definition of it could be subejct to interpretation.
Again, according to my counsel, a litigator himself, most courts will decide in the favor of the innocent party, the tenant, since that's what the act is designed to protect.
Nonetheless, I would still advise those of you renting to tenants pending foreclosure proceedings - or buying defaulted properties from owners with tenants to confirm with competent counsel, as every state has different statutes with respect to foreclosure and tenants.
