Trying to Secure my first RE investment property, would like some opinions.

[Fong Xiong]

So, I've chanced upon a 4flex 16bd 8ba multifamily property, and the seller's agent isn't doing their best job listing the property so it's been on zillow for a few months now. But he refuses to talk anything in regards to creative financing. Couldn't really answer some of my inquiries in regards to the property itself. 

Is there a reason why seller's agent are so against creative financing? I have an offer that could benefit both the seller and I but it seems the seller's agent won't acknowledge the offer. The seller's equity on the property is no more than $70K at best, and I'm willing to pay their asking price. But seller's agent won't entertain the offer. At their asking price, the seller would net proceeds no more than $15K-$20K at best after all fees that would eat up her net proceeds.

PP asking: $620,000
Home was bought: In 2018 @ $550,000

Offer was to pay her cash $20K, possibly 30K if she's willing to finance me the $40K on a favorable term. 
Any funds still owed, if "she got kidnap by aliens"(Got it from Pace Morby) the proceeds would continue to be paid to her kids or family members. 

So I went ahead used my own resource to trace the owner of the property, and it seems to be a lady in her mid 70's who is living outside the state. So I've tried reaching out but couldn't get ahold of her. Whether through phone call and leaving a voicemail or via SMS text messaging. My sources also gives me contact information of her relative. Is it ideal for me to proceed to contact her spouse or family members? Is it weird or rude in any way for me to proceed with this thought? Will I be offending the "owner" in any way by contacting her family member just to get ahold of her? 

My thought on this is the following:

1.) Maybe when I called from an unknown number that is unfamiliar to her, she probably just went ahead and block me or marked my number as spam since it's also an out of state area code that is calling her.

2.) Maybe health conditions is the reason why and she isn't able to return my call and why she is selling the property with little to no equity when she could hold it for for a year or two for a larger equity. Considering the place is a few block away from a University I attended and the rent cost for such area is great. Calculating cost for cash flow is about $1600/month for the property.

I also entertained the idea of mailing out my offer for her property, but my sources is showing more than 1 "current" address so I was skeptical about entertaining this idea. Maybe I could try other source to find her actual current address. 

Any ideas or advice whether it be on better structuring my offer or how I should proceed on contacting her in regards to buying her property would be highly appreciated! I'm still very new to RE investing so please don't mind my inexperience actions. 

Thanks in advance,
