Managing 9 tenants might be a handful being brand new so a property manager isn't off the table but that would lower the cash flow more than I would like. 

What do you bring to the table?

You can call them what you want but it's still 90% financing and if you make your offer as 80% you're going to get tripped up when you get to the contract which would state you're looking for 80% max in the financing/contingency portion, then later on in the seller's rider where you represent you have the additional 10% cash to bring to the table.

Any wisdom on how to go about this process and not leave any money on the table?

As a bonus my husband and I get to play on the pool tables the few times we have vacancy!

Eat at the dinner table?

I don't hope to get any money back from them, they don't have any assets besides cars, wife owns a business which is probably not documented (office is at home and i haven't found any info suggesting the business is properly documented, licensed etc) and husband gets paid under the table.

Is this how I get a seat at the table, Wall-Street style?

@Robert Cabral If the one person is qualifying for the mortgage, what are the other two bringing to the table? 

Unfortunately for myself renting out rooms is not on the table at this time.
