I found a property but, I'm trying to get in touch with the owner where do I start.

Your bigger issue as as I touched on above is maintaining your corporate veil, otherwise this whole exercise of using a LLC is moot and you'll have a big surprise if you are ever sued.As far as choosing a name, certainly using the street address is very common. 

I’ve used QuickBooks but have only touched the surface.

Properties which banks won't touch because they are beat up. 

Same thing goes for people who are extremely lazy by nature, and are not willing to endure any effort or sacrifice to maximize their product's potential.Conversely, big ego people, ones that think they, and everything they touch, is gold, often set rates far higher than they can reasonably get - and then raise hell about the tenant pool, other landlords, tax cuts, and everything else under the sun when the unit sits there vacant, forever.

I will get in touch with the people leading the group and hopefully contribute!

v=5VkacqWgeXIWe should keep in touch. 

Feel free to PM me and we can touch base.

I'll join the FB group so that we can all stay in touch there as well.Look forward to meeting you guys soon.

You can't do anything to speed up the process,mother than providing proof of your ability to buy up front, and be responsive to counters once you get that point, and stay in touch with whoever is negotiating with the bank.
