You're not a charity, you're running a business.

Put the property in a trust for the benefit of a charity.

Maybe pick a charity in your area and give the money to them in your referral's name.  

Quick suggestion here would be to make them tangentially related to income- for example you want to give 5,000$ to a charity of your choice.

I do not want to fall behind market rents, I want to contribute to setting market rents and I do not want to turn my business into a charity by supplementing tenants rent.

If I buy the house I can't just break the lease, it must be honored, but I don't want a year of someone paying 30% market rent.It must be nice to be able to run a charity Tom, should I offer to pay their utilities and perhaps buy them a car, because they may be great people?

I don't know why this fascinates me so much (and I recently pitched a reality tv producer about it - with a charity bent to it) but the idea of turning a certain sum into a much larger sum in a time frame captivates me in an unhealthy way.

A bank REO guy does this every day with people who have hundreds of millions to invest in SFRs.In RE investing, you are looking for the magic triad of circumstances:1) Motivated seller - NEEDS to sell ASAP2) Distressed property - will not sell on retail market until it's repaired3) High equity - this gives them the ability to negotiate on price down to where you MUST be if this is a business and not a charity ;-)If all three of those do not exist, the deal could be elusive and you could waste a huge amount of time chasing it.Oh, and the house MUST NOT BE LISTED.

Can someone offer me the early stage process on rehabbing a charred home?

Maybe add in to the lease that all police reports involving problems caused by tenants, or their guests, will result in a $100 fine, to be donated to a charity benefiting police widows and children.
