In terms of cash flow, depending on the market you are interested in.

Some insurance agents are still sending me the proof each year...So, i guess it depends on your state and locatlity... 

It depends what the purpose are you trying to achieve when you're tapping/pulling the funds from your house.

If you have the time though, you can learn all of this on Bigger Pockets and on the internet. 

Definitely not oversaturated; however it depends what areas you're looking.I wouldn't rule out near OSU.

Either way, depending on your relationship with this person, I would need a whole lot more than $200-300/month for exposing myself to the that kind of debt.

This really depends on your financial situation.

Depending on the price point of the properties you're pursuing, the % of fees can be high.As far as finding deals...

Minimum down payment ranges from 15-25% depending on the lender. 

@Chris Seveney, I would first say it depends on your goals, whether you are boots on the ground local or not, and what you're bringing to the deal making table.If you need a flow of deals, you probably need to be on those wholesalers' lists, a good agent, and to do some mailer prospecting.
