I have been unable to find much info on them online so was hoping the BP community may have some experiences to share. 

You can file the LLC online for $99 in Ohio.

Look up her name at the Recorder's office to see if you can find any more information or deeds filed with her on it.You could also try scanning through the articles of organization for her LLC on the SOS website.You could try truepeoplesearch or thatsthem or other online resources to see if any family members come up and repeat all these processes with them.You could also chat up your other neighbors and see if any of them know how to reach her.If you can identify a previous MLS sale, you could contact the agent and involve them in the transaction to get paid if they're able to connect you two and you end up buying the place.If you're hellbent, there's a lot of stuff you can try!

I know there's fishing and fun to be had at South Padre Island, and I've seen online that the food in the RGV is amazing.

Also I'm looking to do the online class if that makes a difference.

I have read online that the IRS would recommend I hold the investment property for at least 2 years but it's not a strict requirement.

There are forms online for this purpose. 

@Iliya Muzychuk I think this will lead to fewer houses and apartments coming online / available which will further hurt the supply of housing. 

If you do decide to do it, I would suggest combining it with an online presence targeting the same areas.

I also have a Facebook group that is great for online networking.
