Key points for buyers to consider: the $65K rehab budget and timeline (45-60 days) are realistic, but transparency on rehab details and potential delays will be important.

This means a new buyer must either already have an account, or must start one and the property starts over with no reviews, etc. 

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.

It’s not the most conventional inventory, but there’s been a fairly consistent pipeline of retiree buyers from what I’ve heard.

I do it on the daily for buyers from all over the US. 

If not they could spend money and time and offend buyers if they update the property incorrectly.There are other options, such as landlording.

and only close IF they find a buyer to either pay for the contract assignment or pay a higher price for the property?  

Quote from @Juliet Silver: It may be an investment, the buyer is working on a variety of scenarios now.

Doing that bit of pre-work might be the difference for a buyer being able to move forward.

Quote from @Max Ferguson: I'd be interested in hearing about it, but I can almost guarantee if you aren't extremely well versed in the local market you will not find an end buyer.
