I am not not super familiar with the auctions or sheiff sales, but if you are interested in NW Indiana consider connecting with @Eudith Vacio who has some property in East Chicago, but works that NW Indiana Coordior and is a top agent!

First, see if you can negotiate replacing the sale contingency with a longer escrow or loan period.

Quote from @Sarah Rhee: I have a real simple rule for investing: never sell an investment unless you can move the money to a better-performing asset, or if the sale will move you closer to your goal.Your situation doesn't meet my rules.

A CT licensed atty will need to be used to close the sale of the property. 

- What are some methods for projecting cash flow from home sales and determining an appropriate discounted cash flow (DCF) rate?

I have a group chat with my tenants that time stamps all communications, and have handymen, plumbers, HVAC techs, etc. in town that communicate well. 

Understand your market - would make it easier to do comps - recent sales, rents, etc.

The only tech company based here that I know of is Neighborly, which has several hundred employees.

Sale price: $163,000 3 bedroom, 2.5 baths and around 2400sqft townhome.

For a standard 3/2 with 1,200 sqft we usually spend 50-80k on a full rehab, 10-15k holding cost, 15-20% profit before tax, 7% cost of sale.
