@Matthew Irish-Jones Thank you for the advice !  

Purchase price: $135,000 Cash invested: $40,000 Sale price: $225,000 COMPLETELY UPDATED Colonial Home for Sale in Ontario Minutes from the Lake & Village!

You may need the money the day of the sale or even up front in some locations , while you may not get the lien or deed for 30+60 days after the sale. 

I think you would be wise to sell and use the VA loan for your new home. 

Your always right even if you're wrong.Let's check next year if we made more profit or if our Occupancy% declined. 

In fact, for tax sales in PA, the parcel number check is usually best performed first, to see what mortgages can be found (if any); seeing a big mortgage means it's best to move on to the next property on the list.And on a side note, IRS liens can be wiped out at foreclosure of any kind, provided the IRS lien is in a junior position and provided that proper notice is served upon the IRS.
