Two story with both bedrooms upstairs, tile downstairs, indoor laundry, W/D convey, one car garage.

Quitclaim deed only conveys whatever interest a party may have in the property (which may be none). 

Conveyance Tax?

I have thought about researching properties in the area and contacting the management companies which run the properties to see if they can convey my interest to the owner / owners or give me the owners contact info so that I can reach out direct.

I’m wondering if anyone has advice on a tactful, yet effective way to convey that the smell isn’t acceptable if she wants to continue living there.

Any key lessons you've learned along the way to convey to tiny house newbies?

The seller cannot convey marketable title... so the deal is dead imo. 

The entity would either need to reinstate with SDAT or, depending upon how much time has passed and the type of entity, they may be able to convey out as part of the "winding up" process.

Ensure that your contract specifies that the property must be conveyed with clear, marketable and insurable titleOther than these two items, a probate sale is like any other sale for you as the Buyer. 

BUT we couldn't convey this information because he blocked us.
