If the auction bid amount was $100,000 and the investor then sells to someone else for $125,000, and the borrower wants to redeem, it is $100,000, plus the additional charges, not $125,000 plus additional charges.The additional charges consist of interest at 7.5% per year, the VALUE of all permanent improvements made after the foreclosure auction, and the cost of all casualty insurance premiums.

Although, I've heard other people say that this is a great way to improve cash flow.Shared utilities can be split still.

For example a 30 year old air conditioner could fail on the first hot day in summer.

I would also recommend checking if your house would be in historic district as that will complicate any exterior improvements now and in the future.If you would like to meet up sometime my husband and I would be willing to help a local investor.

Strictly speaking you would also be prohibited from improving the property yourself because that would be considered a contribution to the property.

.: Have done it, but due to the costs and what my intent was in the long term, I did that as a capital improvement and depreciated it over the lifetime of the equipment.

I also know many landlords whose cash flow never improved due to ever increasing taxes, not to mention vacancy and maintenance and perhaps the all too frequent floods. 

If your credit score is not great, taking the time to improve it will save loads of money.
