Direct Contact with Seller

[Dana Tenebruso]

Hi, I have recently put an offer to purchase on an "on-market" deal for an investment property to add to my portfolio.  After doing some research I realized the Seller has a few other investment properties. If my inclination is right, she may be looking to sell more of her remaining properties and I think it could be an opportunity for both of us to have positive returns by dealing with these other units off-market. I'm wondering if it would be unethical of me to reach out directly to her to discuss the potential to purchase more of her portfolio. We have 2 agents involved in this current purchase so not expecting any change there but wondering if there may be a boundary being crossed if I reach out directly while we are still in this negotiation/due diligence phase. Id appreciate any expert advice as well as personal advise or thoughts!
