House sitters are nice, but they are only human.

They are humans too and can make mistakes.  

Perhaps set a couple of goals: set X amount aside by the end of the year for down-payment and reserve funds; view X many houses at the very low, low and middle price range; take some classes at Home Depot or volunteer at Habitat for Humanity to learn how systems work, etc.

But I do get a diverse cross-section of humanity. 95% of the time, I never even make contact except through emails, and about 1% of my guests must be ninjas, who show up, sleep in a bed, and vanish. 15 minute cleanups are the best!

The natural human persons will be the ones underwritten for creditworthiness and capacity, but vesting, etc, can be in the revocable living trust, allowing heirs to skip probate if you die, and according to some lawyers giving you many of the same protections that LLCs have. 

A revocable living trust is an entity that can get a Fannie loan, but all the underwriting will be identical to if it was the human borrower getting the loan, and the human borrower will sign for it.

However, humans can't search for properties there... it's just for Realtors to log in and add/update/delete listings. 

Before actually closing on the house, I drove out to introduce myself to the new tenants to show them that I'm a real human being and go over changes that would take place for them.  

Grossly simply example to drive the point home that we all carry around most of human knowledge in our pockets. 

On carpet we get a lot of seconds which have such minor flaws that the human eye can't detect.
