I came close to purchasing a few myself but decided to walk away last minute to focus on other projects.

Purchase price: $80,000 Sale price: $105,000 Contributors: Peter Vekselman Partner Driven, in collaboration with Ernest Bannister, successfully completed a deal on N 31st, Philadelphia, PA.

@Theo Sengat that purchase price, you're probably looking at either a major rehab, a more challenging neighborhood, or both. 

Purchase price: $200,000 Cash invested: $70,000 Wife and I finally pulled the trigger on this duplex.

@Tim JohnsonThere are essentially two ways (and a few variations) to purchase this deal, depending on how the owners are selling it:As a going concern:  In this instance you are buying the business, so it is the business you evaluate: assets, liabilities, revenues (historical: 3 - 5 years), operating costs (historical: 3-5 years), future financial projections, goodwill, etc.    

Purchase price: $125,000 Cash invested: $20,000 I love duplex's.

Purchase price: $180,000 Cash invested: $225,000 Current flip.

Purchase price: $100,000 Cash invested: $73,000 Sale price: $267,500 Contributors: Peter Vekselman Partner Driven, in partnership with Francisco Diego, acquired a home on 4th Pl SW, Vero Beach, FL, for $100,000 on 3/31/2022.

My advice would be to see if you can purchase the plans only. 

I currently own one side-by-side duplex in Euclid (purchased end of 2022), and am looking to eventually buy more rental properties, and possibly get into medium term rentals.
