There is an amount that you can distribute from an IRA account to purchase a personal residence.You then might be able to turn the personal residence into an investment property.Best of luck.

I was thinking if I can talk to my neighbor about sharing the cost (I, the landlord, personally provide labor and my neighbor provide material (e.g. fence pickets)).

While personal loss is difficult and understandable, running a business that directly impacts property owners requires a contingency plan.

Whether the seller was open to a buyer commission or not, I wouldn't put an additional cost into any personal purchase.  

I am here to create a business strategy that protects personal and business investments and mitigates risk,  procure a coach or mentor, and set up tax strategies to create long-term wealth for myself and my family. 

And what if the one person you didn't check has a criminal background, has collections, and more?

Any recommendations on Houston REI groups that meet in person or virtually?

I typically don't comment on other's businesses unless I know from personal experience.

If someone injures themselves and sues, they will be suing the LLC and not you personally.

Be prepared to follow up multiple times, using different forms of communication—calls, emails, and if possible, in-person visits to their office.
