In most cases, these types of properties advertised could also come with management or an option for management. 

, I would start advertising on the internet and local newspapers for properties.

I'm not sure how long these homes have been sitting vacant however you will be taking them as is, closing quickly, keeping the homes in the park, advertising these homes to attract a good deal of foot traffic through the park that may help sell other homes, and also attract good buyers that will bring up the value of this community.

Wholesaler's can't ever list the property or advertise it like they own it and are trying to sell it.. because they don't own it.. only the rights to own it.

One of the many ways I use to to acquire properties that have been advertised for tax lien auction is to go directly to the property with the tax sale lien notice.If the house if vacant, I start my search for the ownerI try to make an offer to buy it or control it subject to re-sale by public auctionI sometimes make an offer to buy while doing a joint venture with the seller (I call it a hybrid offer)There are times when the owner just forgot to pay the taxes, or intends to pay them later or just buying some time until the property is sold or refinanced.If it is occupied, I just tell them that as a private service I wanted to inform them that they have rights during the tax sale procedures (I explain their rights and what options they have), many times the owner appreciates this information and may later call you to make an offer.I realize that while on my way to the tax lien property that I will be driving pass hundreds of other properties where I may see a FSBO or a vacant house that might be a prospect for me.I understand the Universal Law a Reciprocity and how it works, to give freely of your service or advise, the law says you will be rewarded sometime in the future when you don't expect it.Helping other is something you can feel good about.Being active in the field is the best way to find good deals (better than letter writing).

Do they have some special some special algorithm that can give them such accuracy on their "Zestimate" like Google uses in it's search advertisements? 

If they had it going on like that, people would be beating their doors down because word of mouth is the best advertisement.

If this offer is not accepted or countered by January 1, this offer becomes null and void and all deposit help by the title company will be returnRemember BANKS  are NOT human.......they are machines.....they don't really care about you or your money, sometimes I think they don't care about the house, there are too many levels in banks for anyone one person to make a decision (unless it is a small local bank or S&L).Send all your correspondence by certified mail, receipt requestedYou should also understand that banks usually do not have legal ownership of the property being sold at a trustee sale and that the final ratification is not completed until the sale is advertised and a judge sign the documents.

How do local lenders advertise their services besides word of mouth and possibly online.
