So for example if you have a house under contract for 50k and they don't owe anything on their mortgage but have an outstanding lien of 15k, the 15k lien amount gets deducted from the 50k at the closing table.

This sounds like an interesting idea but I am not sure this works.Section 121(d)(8)(B) - Exception for sales to related partiesSubparagraph (A) shall not apply to any sale to, or exchange with, any person who bears a relationship to the taxpayer which is described in section 267(b) or 707(b).Section 267(b) mentions An individual and a corporation more than 50 percent in value of the outstanding stock of which is owned, directly or indirectly, by or for such individual;The only way I can see it work is if the owners only 50% or below of the corporation buying the house; interesting idea though.

On the liability side, you include outstanding personal liabilities like mortgages, car loans, and credit card balances. 

Your goals are outstanding and I’m sure many would agree that your 70% savings rule is a great accomplishment in itself!

I worked with two amazing Brokers (Travis and Patrick from Savvy Ent.) and an outstanding loan officer (Isaiah from Cornerstone Mortgage) who really helped pave the way.

On the east side, in Redmond, we are currently living in a property worth probably 1.6 with about 600K outstanding - and a monthly payment of about 4K including mortgage, insurance, property taxes etc.Looking to leave the area.Does it make sense to rent it out given that I’ll probably get 4K in rent?

They are: verifiable income of $5,550 per month, good reference for previous housing history, pass credit check over 650, no outstanding past due obligations, no recent (10 years) bankruptcies, a clean criminal record, and no previous evictions."

But, you still have the loan outstanding...Also, I don't know why you added the whole part about the $2k/mo less... 

However, if you're debt outstanding is significant then a rate term refi might make more sense if you plan to hold onto it for a bit. 

I imagine there were lots of great looking spreadsheets presented to investors in 2022 and 2023 promising outstanding returns and some of those deals are now in trouble.
