However, I don’t yet have the funds for a down payment on another house, and I’m trying to figure out the best option for where to live while I rent the apartment.Do you have any recommendations for managing this transition or tips on finding a temporary place to stay?

Most people bring their own.We also have a bin of razors, q-tips, cotton balls and even a bunch of contact lens cases in the master bath.

That's not even the tip of the iceberg; it's so far away.

Your name and credit would stay with the existing note, which you would keep paying on - ideally yourself with money you receive from the "buyer", because if they don't pay your credit is wrecked and your house is in foreclosure.If you search on here you'll see everyone and their brother looking to do Subto and it's a nightmare unless the buyer has the funds to pay the note off if/when the original lender figures out you don't occupy the property any more and are attempting to do what you want to do, since most loans are going to specify that performance.  

Most local banks and credit unions will have free accounts.You need two accounts: checking and savings. 

Share your stories, tips, and insights!

Thanks in advance for any tips or advice you can share :)

And due diligence is key with good tips from @Mike G.

I suggest 8% for a great credit buyer and higher for one with poorer credit.

But the risk to the seller on this deal is immense you have a guy tying up a property who has no ability to close it and then sell it to whoever will give him money and that person could be nefarious get into title rip rents could give 2 craps about the sellers credit etc etc..
