Do you deny that you're selling people an idea that they can get $42,000 homes, for $4000 down, then resell them for $106,000 with only 18k in repairs?

The ultimate goal is to resell it and make a lil profit

Be mindful/watchful as some may want to resell their properties after they have acquired it at Tax Sale. 

The market trends have no effect on a situation where a seller may become motivated and needs to leave their property (job, divorce, death, etc).If you buy low, you can make money renting or resell at a higher price.  

I am running comps, getting zillow & eppraisal estimates, showing 70% below market, est repairs of 10k - 20k, taking 5K wholesale, and the rehab would still show 30% ROI for resell, or solid rental income.What am I doing wrong?

A lot of them can be portfolio lenders, meaning they originate the loan and then keep it rather than packaging it up and reselling it. 

Are you doing this deal with the TK provider or are you independently purchasing the property, performing the rehab, and reselling?

Jason, a lease to buy sign is probably a red flag meaning someone has already bought the property and is going to resell it to get maximum return.

Hard money won't either since it will only provide a bridge for a few months to a few years.If your only vision is to buy low under Contract for Deed and resell higher, you might contact the heir(s) and determine what one's plans are.

We have the perfect market for reselling as the real estate on the market is limited.
