You are trying to purchase 3 properties with no skin in the game. 

He wants me to have skin in the game, so I've agreed to invest 25% of both the purchase price and rehab costs.

HOWEVER you can tell the judge the time sensitive situation about the pre foreclosure and the urgency to sell the property , the judge will 99% give them a quick order approval to sell the property. 

This is time-sensitive as we are getting ready to close. 

If you found an investor to fund the DP and you got the loan (if you found a bank to do that since you have no skin in the game), then the investor would want at least 80% of the equity, more likely 90%.

They want you to have skin in the game.

Then you might get a little less based off the concept that the investment is less risky when this person puts 'skin in the game'.  

most private lenders would go to about 75% of the purchase price the other option is to see if you can find a seller willing to hold a note for a portion of the last 25% (maybe 10 to 15%) and you can come up with the difference but most lenders want you to have some skin in the game as well 

This especially now as the topic of Airbnb is somewhat sensitive in Hawaii.Hope this helps, brahdah!

At least as an owner with skin in the game, there is motivation to vet short term rentals guest, limit the number of occupants per unit/bedroom, keep the property in good condition with maintenance after every turn, etc.
