Im definitely going to look that up, I could give the tenants the resources and offer a pet fee discount.

This would save the occupant from a foreclosure, and could get you a nice discount on the note.  

Buy at a 10-20% discount, so my purchase price would be $74-90K (20% down payment).

I can understand if it can really add value but I have never heard renters say man the place was great but that flat roof I just can't rent there or I need a rent discount for flat roofs.

At that point agents only show when they think it's a deal and then the offers are often discounted as well.

Even if you are paying cash, make sure you are getting a significant discount because when you go to sell it you will have a harder time.  

I did some googling and found at least one program, called the "Good Neighbor Next Door" program, which offers a whopping 50% discount off the purchase price of a home in select revitalization areas providing you live there for at least 36months. 

Secondly, I'm trying to avoid marketing to these motivated sellers as a "hoity toity" real estate investment firm called "Capitol Wealth Builders" when I'm trying to buy their property for steep discounts, and felt "SellHomeNowDMV" could just be a domain I own and do business as when marketing to these folks (postcards, craigslist, yellow letters, etc.). 

Are you purchasing at a discount?

You are assuming some risk that the Tax Deed could be overturned and you loose the property if the county did not do everything 100% correctly.I own many houses that have tax deeds and this does not scare me because I understand them, but I would at least do a title search and make sure the county notified all owners of record and any mortgage holders.There should still be a steep discount on any property bought that has a Tax Deed.Like I said $2000 would be money well spent for a clear title.
