Yes you can, you're just selling like any other sale.

For me as well as the seller.First, you have to define Sub to financing.Do you mean the reckless kind where you overpay for a property, take over the financing and borrow from others to cover closing costs and holding costs when you have no money, no credit, no income, no reserves and can't tell a warranty deed from a deed of trust and you close on the kitchen counteror do you meanbuying below market value, already having a nice income, having reserves, using escrow and title, already understanding the due on sale clause, have done a lot of creative purchases and know when to use and when not to use creative finance and how to recover if something goes amiss?

Cold calling, mailers, signs, google/Facebook, RE meetups, RE agents are all ways a whole sales would find deals

This is not uncommon and actual more typical as it is based on sales price and even though the first appraisal was $130k the new one gets reset based on its recent sale and home prices are not up 10% over a few months.You are going to have a hard time getting a lender to use other comps compared to this home as it recently sold.

Transfer from personal name to LLC/Due On Sale ClauseIf one is transferring property title from personal name, a Grant/Warranty Deed would be drafted/recorded to transfer title.

How do you advertise it for sale?

The problem is that most sellers aren't comfortable reviewing purchase and sale agreements.

Hi Timothy,We have a phenomenal BRRRR product. 

These guys are the real deal especially Lee Arnold yes he is a sales guy but the dude has been doing real estate since '96 he knows what he is talking about.

The 1031 must be a sale of investment property followed by the purchase of investment property.
