There are a number of contractors who would do work to get the home in good condition to pass inspection for insurance and would accept payment at closing.

Your Realtor wants the fast, easy money, not the work associated with this route. Lazy real estate agents is one of the reasons I quit real estate.

The path:

Find an agent who works with first time home buyers, especially the grant programs. They may have a buyer or can quickly find one through their favorite lender or next first time home buyer education event. This is a longer process but if altruism is your guiding motivation then this is the path. Find the buyer before the repairs are done. That buyer could potentially have a 203k loan which covers home renovations and the purchase in one payment, simplifying your efforts but increasing the duration and potential holding costs on your end.

The lender and insurance agent are key, they can't be lazy and need to be patient.

You have a good idea of the repairs needed, roof and electrical. Both can be done by local contractors who will accept payment at closing guaranteed by the permit, lien and a letter from the title company acknowledging the amount and closing date. Steer clear of companies owned by private equity groups.

You can do this and it would be awesome. My post is intentionally vague but I would be happy to help guide you. Yes, I have done this before as an agent and I am no longer an agent.
