Is there something else the partner can bring to the table other than just a signature?

Finding myself one month ahead on my mortgage had become good mental headspace when it came to managing the anxieties of rentals and reliably took a considerable amount of solid fear off the table whether that fear was rational and justified or not.

Most people struggle getting started, but it seems like you are in a position to take advantage of what you can bring to the table.

It’s on the market, they just had an offer on the table but buyers backed out after a 4 point inspection.

You certainly could offer $65k, but the seller would have to bring about $10k to the closing table to settle the mortgage. 

Both of us are satisfied with our arrangement since I can bring those skills to the table that they don't have.

This means that you will have to come to the table with some of your own cash, as well as float the first construction draw.Now, given this, why would anyone not use leverage? 

Throwing a win win situation to the table, what if we meet for a beer I share all I have learned and you tell me the secret spots to visit in the island?

You have money left over in case something else comes up and if you paid cash, I'm going to guess you still have a healthy cash flow after your expenses making it is a great return on your initial investment of $50K.Option 3 would be off the table as I don't think things will change that much in 3 weeks.
