I am thinking the easiest way would be promissory note, but I was curious if there was any way that I could secure their respective liens on the property.

Originally posted by @Michael Lewis:Your math is wrong the 60k profit a year on a 500k investment is 12% But you don't see that equity until you sell the place, so you would also have to include the opportunity cost of tying up $500k in cash.The only way you could see that down payment back in cash is to take part of it out as a loan secured by the property.

Hi @Andrew Pappas,I would recommend securing the property using other financial means, removing him entirely.

Secure a title commitment asap.

You say he cleaned it well enough to receive a portion of his security deposit back?

Travel credit cards are good for the signup bonuses, for which The return is much higher than regular cashback card. 

I’ve secured a mortgage through Boiling Springs Savings Bank on an investment property several years ago.

If you go that route make sure they use the correct cement, you can't use regular mortar.  

I feel like just closing without the added work of securing financing will make the process less stressful but it's a lot of money.

Some of them are referrals or have good reviews online.I have some questions that I plan to ask, including if they are insured, licensed, and to see if they do work on investment properties, rather than regular homes.
