It can be quite intimidating as a newbie trying to decipher what the best method is but I understand there is not one right solution.

I would really like to help her, but wanted to see if any of you could give me feedback if this is even do-able or not, and if so what are some solutions that I can give her?

There are no easy, obvious solutions. 

My solution is offer the homeowner their full asking price if they allow us to do a conventional 80% loan and seller financing the the 20% needed to stay away from paying PMI. 

Expressing concerns or making a change were both acceptable solutions. 

I've done one in ~9 weeks pay cash for purchase, then use delayed finance for the refi. you must use YOUR funds to use delayed finance and you must have a tenant in place when the appraisal is done. if you're using outside funds or a loan at the time of purchase you're likely limited to 6 month seasoning unless you can find a creative lending solution. 

That would seem to be the simplest solution to me.

We also recently started a wholesaling business, Gainesville Property Solutions.

In 32221 alone, GE oil and Gas manufacturing gas appliances, Jinko Solar, Bridgestone tires, Wayfair is building 1 million sq ft facility, LNG Eagle clean fuel manufacturing, CTSINTERNATIONAL  Logistics Solutions Group.Industry West FurnishingsCecil Commerce center, FSCJ Cecil Campus College, Equestrian Center is also a large venue for concerts and what not. 2000 acres of Normandy are being rezoned to a much higher density, 5000 roofson  ,a 3.2 mi stretch of Nornandy blvd. 1139 new apartments were approved Normandy west in 32221as well.

Giving them 60 days notice and free month of rent might cost them $1300, but lets say you roll that $1300 into the purchase price...not going to make much of a difference on your debt service.TL;DR -- check local laws, then try and find a solution that might make everyone happy.
