Since I ended up putting so little down on my primary and have savings left over, last week I was pre-approved for 25% down on a duplex out of state at 4.75%. 

However, I have a comfortable allocation of secured funds for investing and there other reasons I believe I'd qualify for other loan options.My question is, how do I see about getting additional pre-qualifications on identified properties/home values without lenders pulling my credit?

If the tenant hasn't paid, you need to get the eviction case reinstated.

The aggregate UPB calculation does not include the mortgages and HELOCs that are on the subject property,the borrower’s principal residence,properties that are sold or pending sale, andaccounts that will be paid by closing (or omitted in DU on the online loan application).

So my question is, when partnering with an investor/friend/family member how do you legally set up the purchase to ensure cash flows are paid out as agreed?

There is just little incentive for investors to rehab them and then get penalized over single family.I actively own both single and multi family rentals in Memphis and if I was selling the duplex would be the first to go.I hope the advice is worth what you paid for it !!!

There are many Real Estate Clubs in San Diego (some free, some paid) that offer networking and education.

The points are rolled into the loan so they are paid at refinance.

He tells me he will take  $ 1500 for it .   1/2 of what he paid .  

Otherwise he can give notice to the tenants but personally I would not want the current owner getting a lease in place now and you don't own it so you can't lease it pre-closing.
