We can find everything but these numbers, leaving me at a loss when trying to do comps of our properties with properties of similar attributes in the surrounding areas.

PGI = 2470 vacancy loss = 4% 100 EGI = 2370 property tax = 309.4 homeowners ins = 156.6 utilities(common/water)= 165 repairs and maint = 10% 250 NOI = 1489 debt service: PI = 1101.6 monthly PMI 253 positive cashflow 134 Explanation: I am pretty good with evaluating tenants, and keeping them long term.

How do I record this loss/clear this in Quickbooks. 

As I see it, there were several downsides at the time including and clearly not limited to:Equity lossTightening of CreditOver-Leveraged folks losing homes to foreclosureJob losses causing some folks to not be able to meet financial obligations (rents)But these could easily be offset by some of the positives at the time, particularly for those in a buy and hold position:Increased pool of renters as folks lost their homesIncreased demand forcing rental prices up (after some period of time of course)Banks (private lenders??)

First, each property needs a Landlord  policy(LP), which provides fire, protects the lender from loss and you from public liability (some up to 1mill ).Second, an umbrella policy adds protection on and above the LP.I hand each tenant a copy of Renters Insurance so they can protect themselves.

Or, someone realized they had screwed up, and are dumping them at a loss to minimize further losses.You guys do realize that to collect your money, if they are not redeemed , you have to send them to a tax deed auction.  

One thing that threw me off recently was that a lender required for me to get "Rental Loss Insurance" .

In the long run, does it make sense to keep on pumping money to keep these properties afloat or should I bite the bullet, sell them at a loss and settle with the bank?

I corrected it above.The last chart on this site:Calculated Risk Unemployment Chartshows the percent job losses relative to peak employment month.

I had only invested a few K so the losses didn't break me, but it did make me very skeptical of what would have otherwise been seemed a good investment.
