Renter investing in my purchase

[Ross Spindler]

Hey everyone,  

I have a unique situation that I'd like your input on. 

I have a tenant who got a few $100k as inheritance. She doesn't want to spend it all on a house and would prefer to keep renting from me for $1500 per month. Her biggest stresses are not knowing how to invest and not having a place to rent because it's very competitive in Florida.  

I have a couple duplexes, good income, and great credit... but not enough cash for my next multifamily down-payment.  

Would you take $100k from your tenant in exchange for 10 years of future rent? At $1500 a month... she'd basically be paying 5.5 years worth of rent but getting 10 years worth. (Almost doubling her money)

I'd lose out on the $1500 rent for 10 years, but likely make it up by putting that cash into another property that can flow close to $1500 monthly. 

also, I think our ages matter to better explain motivation in this situation.  I'm 33 and she's 60. 

Would you take this deal? What parts aren't I considering?
