I then ran a different ad and the cost was only 6 cents per contact. 3 cents higher than FB lowest estimate.

Am I getting greedy to ask for an additional seller credit at closing to help offset some of repairs needed?

(May also cut significantly into the current cash flow on it)I know you mentioned not doing a HELOC on my primary, but wouldn't it be advantageous to have the ability to pay off the line of credit instead of be stuck in a payment that is much higher? 

For me as well as the seller.First, you have to define Sub to financing.Do you mean the reckless kind where you overpay for a property, take over the financing and borrow from others to cover closing costs and holding costs when you have no money, no credit, no income, no reserves and can't tell a warranty deed from a deed of trust and you close on the kitchen counteror do you meanbuying below market value, already having a nice income, having reserves, using escrow and title, already understanding the due on sale clause, have done a lot of creative purchases and know when to use and when not to use creative finance and how to recover if something goes amiss?

THANKS Your local credit union might be your best bet.

Specifically, I am looking at partnering with an individual who owns securities (stock and mutual funds) having them take out a line of credit against their portfolio (SBLOC) at a low interest rate, and using that to purchase properties rather than using a mortgage.

@Helena Goyvaerts rate for a 30-year fix would be at least 8.5% with some points (1% of loan amount).Most DSR lenders have a minimum credit score requirement from the applicant.

Some will be ok in 2nd position and some will not and force you to refinance out the first - but those are options that are probably cheaper than credit cards 

Other than paying for an appraisal or BPO (and maybe a credit report), you should not pay a lender anything until your loan funds.

I predict that the guys who are fully leveraged and cash flowing $100 per month will be motivated sellers when the next big correction happens.actually its either them or they walk and its their lenders selling that is what happened in that time period.. and was pronounced in certain markets.for me personally  I don't want to risk  my credit and finances and borrow 75k to make 1200 a year... or even 2400 a year if its a market that has a history of no appreciation and I don't feel there is going to be any significant appreciation.. 2 to 3% a year does not cut it.but I will take 500 a month negative or 10k a month negative if I think there are huge gains at the other end..
