I hosted attorney panels in local REI clubs, and there never was any consensus.In our great state of Texas, your best option could be a Series LLC: one LLC that has individual compartments for each property.

You may find them excited about either option.

Why would you want to work with a realtor (I know she is your wife, no offense) who knows none of the agents, does not know the paperwork or the process (they don't teach you this in the class) when your primary residence is on the line.Brokerage options vary, but if you just choose the cheapest one and use your wife, you will pay for it later.

Another option is private money / hard money. 

Secure funding for your flip through options like hard money loans, private investors, or leveraging your home's equity with a HELOC.

For almost all investors, buying a property off of the MLS at market price in a good location to hold for 10-20 years is the best option. 

Until I find my niche, I am keeping my options open. 

Yes, we are looking for some options if you are willing to share, we'd appreciate it!

I guess the other option is to use a property mgmt company to find a tenant for you, but I just thought it would be interesting if there's a site where the landlord can peruse a list of quality tenants and reach out to them directly! 

Could house hacking in an area you're currently living in be a better option?
