For some buyers it would end up being less than a 2.5-3% commish, and for others more.The tricky part for the buyer is it would have to come out of their pocket in addition to the down payment, whereas a commission paid by the seller at closing is included in the purchase price and absorbed into their loan (usually unless paying cash obviously) so the buyer only has to make the down payment out of pocket.

I see you did a loan sizing down below on your sheet, but I'm thinking that's on current NOI and not on a 7-year projection.

You have a bigger loan, but not a bigger tax basis.

The DSCR loan would allow you to qualify based on the rent you are collecting and get up to 75% of the value (175 x 0.75 = 131.25k, minus 20k payoff and closing costs.You could get a line of credit or a bridge loan against it to borrow money, but it would be higher interest.

Do the math at a 6% loan rate.There's a reason many apartment buildings have been converted to condos and sold.

There are services like Blockfi, Unchained Capital, and many others will will give you a short-term loan backed by your crypto assets.

Rates are high, usually in the high 8s or low 9s, and you may pay 2-4 points on the loan. 

Just because you get a loan approval does not always mean you should move forward with it.

.- Do you have 200-250k cash, or is that what you can get with your loan amount?

As far as your next property, if you are already considering moving you will get better loan options + interest rates if you decide to live in the next property and rent out your current house.
