Win-win.

Tell them "it's a win-win situation for both of us"  and you're doing this because you don't want s/he or them to have an eviction on their record which will affect their ability to rent in the future.

I've acquired mobiles in the same price range; I'm holding and renting them, but based on recent sales in the same park, I'll bet I could sell them for a good price.

They may well wait until the last minute to do that.As with many things in the business, there are battles you can win and battles you cannot.  

If it was between me and an adult fighting it out for their house, the adult would win every time. 

i am looking at a commercial building asking price 1.5million, 15 units 13 are occupied.rent roll is 171k when fully occupied, presently its 131k expense are 60kthe seller is not motivated, so how do I structure the deal so we both win. 

But then again retirement is still many, many years off for me, so I'm thinking my best strategy may be to bet on Southern California appreciation for the long haul...I don't plan to quit my job any time soon, and I'd take 1% greater average year-over-year appreciation over the next 30 years over an extra couple hundred bucks monthly cash flow per door by picking up property in Cleveland or Indianapolis...decisions, decisions...Let's say you were in your 20s and could do it over again.  

If you're talking buy and hold your best bet for affordability and appreciation are Milwaukie and Lents.

Looking in the Long Beach Orange County maybe Riverside, CA area.I've been reading a lot of BP post and seems like multi family homes would be the best bet going off some prices I see and house hacking tips.First time buyer so I know FHA will be the best as far as loans are concern.

I bet if you get your next deal under contract and post it on the marketplace here you will find plenty of people wanting to work with you.
