@Llpeng WuAs Brian posted, you have the title, you don't need consent to sell for cash or a financed transaction that pays off the mortgage, you do with any seller financing by you if that existing mortgage is not paid off. :)

Yes, 100% legal to ask and offer cash and come to an agreement.  100% illegal to do anything to force them to move, make their life uncomfortable etc... prior to lease end.

I'm looking for someone to help with data analytics, quickbooks reconciling and such, CRM management, transaction coordination, and basically any other task I can outsource.

I am considering the option to obtain my Colorado real estate license to be used as a transaction coordinator.
