NEWBIE-In love with an AS-IS REO.Does this deal/setup sound FISHY?

[Angelina Grace]

I am a complete newbie in the REO arena, Ive been searching online for about a month now for answers and finally found this site.

Background: I currently own a home but I have a tenant moving in June 1st.
My husband and I need to find a place in at worst two months. He works 7 hrs away from home so we decided to move closer so that our family can stay together however I want to purchase a property that can become a 2nd rental eventually because his company is expanding and keeps moving them around to different states.

Main:
We have fallen in love with a REO that smells like it was formerly an animal shelter and has black mold on the sunroom's ceiling (because whoever built it as an addition wasnt too brilliant re: the roof's pitch from the main house.

My husband once worked in roofing and construction years ago and could do the reno mostly by himself if all thats wrong is the flooring (source of smell) and the roof.

However when I checked the county's GIS map the house that is being advertised is not in the location on the map that it should be according to what we saw in person. The parcel no. and lot number given for the house showed up on the map two properties down - a vacant lot.

Even if the gis map got the house numbers mixed up this is confusing because the houses go in ascending order and the house really shouldn't be the number it claims to be online.

Another issue I have is that this company says that it only issues quit claim deeds or limited warranty deeds. Yet in an email the agent told me that the bank doesn't own it - apparently this is a company that bought the property from the bank. Online it said that the property was sold for just over $1,000
The property is now listed for $23,000 with an option of owner financing at $750 down and $250 thereafter.

We really want the house and its zillow 'guesstimate' is $43,000 however similar listings in the area go for $75K- $115K. Before the bank had it, it was sold for $60K in 2004. We could go the owner financing route because then if in a few weeks we find out something is terribly wrong we can walk away only having lost a little. However then if we stayed we would have to pay the full 23K. I was thinking of waiting for it to be on the market 30 days and then offering $8K -10K cash. Is that too much of a lowball offer? You can hardly breathe when you walk into the property the smell is that bad. Lets not forget the mold and the confusing GiS map concern.

I have a real estate lawyer, I plan to apply for title insurance but i dont know if they will offer title insurance on a REO if all they give me is a quit claim deed or limited warranty deed.

Im worried. I take risks often and almost always profit but this is a new area for me and I feel absolutely clueless even though Ive spent countless hours researching. Any helpful advice or commentary would be so very appreciated.
Does this REO setup seem shady?

HELP!!
