Jesse, When looking for a home needing some repairs you should find out what the price homes are selling or renting in the past 3 months. Determine what MINIMUM profit margin you want and budget based upon those numbers. When selling, there will be Title, State and County fees of approximately 2.5 percent.
If you rent and use a property manager last year they started at $250 per month plus costs incurred.
If your question is, how much are fixer uppers in Detroit, homes are available starting at $5,000. Of course these may not have doors, plumbing, or siding because of thieves.
