Explain this logic, please. How is it "better"? Using which criteria?
I totally understand people who prefer a better current lifestyle if a large expensive house makes them happy.
[1] That is, assuming a decent appreciation of home values. In Detroit, say, this advice wouldn't hold because the homes are worthless investments and you want the rent income instead.
As an investment vehicle, there are very few investments which can be diversified as much as rental properties. In my experience there are also very few investments with the level of return of rental properties. [2]
[1] I am not a lawyer, a CPA, or a tax attorney. I do have all three of these people on retainer. If you would like to know how set this up and make sure to get the most advantageous tax positions and financial positions from your investments, please hire people like this to tell you what to do. Also, do not forget to interview a few attorneys and tax professionals before hiring.
[2] My experience: I currently own 12 properties of three different rental categories in 3 different states.
Also cheaper homes will appreciate more. For example a $1M home can only go up so much if that's already the top end of a market but two $500k homes can go up a lot more.
Is that the crux of your argument?
Maybe the general disagreement here comes from an inequality vein. You know, McMansions are nothing to brag about, they aren't like... real ... mansions. Just cookie cutter larger homes that are dime a dozen.

It's fine if the wealthy choose to give away some or all of their wealth, but it must be voluntary. Anything else is called "theft" - or the closely related concept of "taxation".
My advice: be careful choosing property management agents. Get referrals and communicate clearly what you expect as far as them quickly fixing problems, providing receipts, etc.
My meta advice: prefer buying modest homes to live in, not MacMansions, and try to hang on to them as rentals as you move. It is a good way for someone in the "middle class" to accrue resources. It is better to live in a modest home and have separate income property than to just own a huge/expensive house that you live in.
