I find them all to be good options. 

It positions you well for real estate success but don't stop there, explore different investment options and build connections with people in the field.

If you are looking to get cash now I would move forward with a delayed finance.If you are looking to pull out the most amount of money possible, I'd look at a cash out refinance.Another option would be to do a bridge delayed finance, pull out some cash now, then refinance again 6 months down the line when the seasoning period is up.I would love to connect and share some ideas as I am working a couple similar loans as is right now.

If a wholesale deal yields $10,000 on the low end, the value here far exceeds that.Also, I understand that Affirm is optional.

You can't count on believing that the family member will not produce a handwritten lease (real or not), or other paperwork & tactics, to throw a big old wrench in your initial/expected timeline.You CAN expect that if they see you as the big old rich/developer/bad guy enemy, they will do as much damage as they can, and drag their feet as long as possible.See if you can feel out what the relative actually wants/ needs, connect/come prepared with info on resources for local "housing help" options, etc (perhaps), and figure out what you can do to solve the problem (cash for keys with an incentive for quicker move out timeframe?

If not, offering seller financing isn't an option. 

In my mind there are only a few options: 1.

I’m trying to see if I have any options with the seller.

I would suggest you find an agent in your area from bigger pockets and go from there.

Leveraging financing options with a HML or PML can offer flexibility, scalability.
