That sounds like a good strategy to wholesale deals to help you fund long term rentals.

What if the lender (in the future) wants to have a 70% LTV instead of 75% LTV?

Stock market is not a good place for money that your planning to use relatively soon and bond funds, CDs, and money market funds don't offer much ROI.

I want to put in an offer for a property, it listed on MLS for 120k, want to put in an offer for 70k but my agents said I would need the fund in my bank first.

They had held up my release of funds for over a week after signing while they waited for the invoice and then paid it and closed out my account the day they received it. 

Do you have any tips for who to contact for lending, or creative funding?

Prior to that, you may be able to get a loan based upon the appraised value, but it will typically be at a lower LTV which will basically put you in the same position as if it were based upon purchase price.

Hi bp,Are you able to get a cash of refi of 75% ltv on a 2 unit property?

Do you have funds to cover repairs and turnover...
