You are wasting money every day on unnecessary toys and luxuries.

They are retired and do not want to claim any more income than they already do.Can this be structured in order to prevent them from having to claim income as I repay the loan?

But tax laws are generally set up to try to prevent this scenario, wherein someone took advantage of depreciation laws and earned years of tax-free income, and then tries to profit a second time from the sale of the asset without paying taxes on that asset.

It isn't like borrowing from a business insofar as they have their own goals, and if they change their mind about something, can become an unnecessary distraction...i.e. calling once a week asking about the status of the investment and the like. 

Is that not what a broker system is designed to prevent?

If so, there should be nothing preventing you putting it under contract and trying to find a buyer.

This is probably one of the most expensive fixes and for simple cracks I see it as one of the more unnecessary.

I appreciate your time and energy on this as it will definitely keep me focused and prevent me from working with someone that may not be the right fit.

I could go a conservative route with them that could prevent or reduce the risk of that happening.  

You may just have to pay 1 year of taxes to prevent that.
