A portfolio lender is your best bet.

@Robere Istatia, for a performing note none of your money is involved.

I bet you run a seriously amazing, and legit, business.I also have a soft spot for this because I volunteer in California prisons, one day a month and six full weekends a year, and I work with the inmates directly and I know for a fact that so many of them have your kind of mind and drive and skill.

It is very expensive and time consuming to go to court for both parties involved in a claim.No legal advice given.

I bet @Jon Holdman has a good answer to this - per usual.

Because of the very long process involved in the pre-sale, and the fact that post-sale challenges must have good cause, post-sale challenges rarely happen.Also, at least with the tax sales I'm familiar with, you need a check in the amount you are willing to pay for that property on the day of the tax sale. 

If so, would you mind explaining the steps that were involved that would differ from a residential Brrrr?

Who is it that has 6 months of time and effort involved in the scenario above?

I bet they change their tune when you ask for this.

Overall this is not a deal I would involve myself in.
