Mainly because rentals for me are "long term slow money" and I use the chunks of cash from flips to buy and/or pay down the rental balances (increased cash flow, lower debt, etc).

Put it on an auction site starting at your loan balance?

@Samuel Metcalf- thanks   1) I would recomend getting a HELOC in place on your primary residence duplex  for  as much as  possible...this should be available for  free or a low  cost and the rate will be variable in the  8-11%  range ...prime rate +  margin of  1-3% ) ...the min payment is in interest only payment on outstanding balance   2)  use the heloc for the  remodeling  costs ...pay it down as  agressively as you can   3) on the  purchase of the investmenet  1 unit -  you are  allowed to put as little as 15%  of the price for your down payment ...the pricing you get for the loan will improve  as your down payment  grows so you might look at  75% /  80%  and  85%  ltv  options 

The tangible nature of property investment, coupled with the potential for rental income and capital appreciation, offers a balanced risk-reward ratio.

Asking is $1M-current loan is $650k)The sellers want to avoid carrying the balance $350k balance, even though the simplest thing is if I could make amortized payments on the balance.

@Devon Morrissey most covered by @Samuel EddingerWill add this, check out your state laws and also the PENALTIES.We know how it works in Michigan, where we do biz, and so we balance risk vs reward. 

To some degree I imagine this would balance out a bit.

I also have the cash for the balance on the loan just in case. 

My remaining mortgage balance is around $94k, so you can see that I’m already facing a significant loss in selling this property.

Recent history has shown that even with liquidity injections and reductions in the Fed's balance sheet, mortgage rates may not align with expectations.Bank Constraints and Real Estate Debt: A significant concern looming over the CRE market is the staggering amount of commercial real estate debt maturing, coupled with the constraints faced by banks.
