So all of our idle funds and regular checking deposits sit on the outstanding balance and save us a ton of interest cost.

Also if you know anybody with MLS access see if there are any outstanding mortgages on the house.  

Eventually I fired them and now I do not know haw to clime the outstanding balance for those tenants.

The outstanding loan balance  exceeded the purchase price - the deal is off.

Solve the outstanding debt latter, assuming it does not disqualify the transaction.

Any outstanding medical bills may have to be paid.

Here are reasons some people do not take loans:1) Poor/mediocre credit2) Unable to take more (due to outstanding lines of credit). 3) Low appetite for risk and subsequent backup plans.4) Foreclosure, short sale, and mom & pop deals that require cash (for ease of transaction).5) Access to plenty of capital (this is a problem most wish they had).Regardless of your case, any of the above is a viable reason not to take financing.

Well, there's probabaly a reason they are all outstanding.

Steverealtor access on GSMLS won't show you what is paid or outstanding on property taxes.Need to dig little deaper  for this info.ThxChris

Two of the ones referred to me were outstanding and delivered on time.
