An LLC is likely a good tool, but how effective it is and how to use it depends on you.  

This is not new, people have been voicing your thoughts for a long time,.

You effectively hire an asset manager and they manage the property for you - the only thing you do after the wire is receive reports and distributions (hopefully!).  

There are some tools online that you can use to help "manage" you property, this is effective and cost efficient for portfolios less than 5 units.

This will effect their debt ratios etc.

These factors help create a ceiling effect--where, no matter how much the house is worth, there's a limit on how much you can charge in rent.And, as you mentioned--if leverage is involved, the debt service of a more expensive property often overshadows how much you can charge in rent.These factors contribute to rent not increasing proportionately with the price of the house (and there are probably other factors too, that I'm just not thinking of at the moment...haven't had my coffee yet).Having said that, there are some extremely niche markets with rental properties that cater to multi millionaires, and which are extremely expensive (certain areas of LA, for instance...probably the French Riviera --where there are probably lots of transient tenants worth tens or hundreds of millions)...but, those types of markets are obviously the exception to the rule...Good luck out there!

Older people remember voices and names and how you made them feel, not postcards.

On owner occupied residences you can put down as little as 3.5% (sometimes will seller subsidy’s and certain loan programs it can be effectively less than that.) however with rates above 6 generally I recommend people try to put around 10% down to keep their payment reasonable.

Following the lead of cities like San Francisco and working directly with Airbnb would be most effective.
