Some of the data points you can view include:- Rental Vacancy Rates- Median Household Incomes- Median Rents- Educational Attainment Rates- Population Counts and Changes- Home Values- Poverty Statistics  and much more.This will give you a pretty good idea of what to expect before ever stepping foot in the neighborhood you are researching. 

This would remove landlords’ incentives to decrease the housing supply and could provide households with the insurance they desire.To me that's pretty positive.

Likewise, transforming the main house into {4} apartments or condominiums would necessitate a similar or greater sacrifice to meed modern fire codes and to insulate and install separate HVAC for each.  

That is how sure I am that it does not cost $30,000 to install an electrical pole.How about my post "How does a condominium owner make money?"...

I am a 17 year old with (obviously) no experience in real estate, I was wondering how I could go about renting one house to multiple people. would I have to make one person the head of household, or could I simply collect rent from each person individually?  

Other friends who had less growing up would strive for something better or copy their household's example.

@Alex SilangHere are numbers for you to consider.There are 9.63M millionaires in the U.S.There are 7.9M households in the U.S. with a net worth between $1M - $5M.There are 1,140,000 households in the U.S. with a networth more than $5M.There are only 350,000 households in the U.S. with a networth of $10MThere are 77,500 households in the U.S. with a networth of $30M There are less 10,000 households in the U.S. with a networth of $100Mand there are approximately 400 households in the U.S. with a networth of $1 billion.If you are in your 40s, you need a networth of $6.8 million to be in the top 1% of wealth and in your 60s you need a networth of $10 million.You have to have to be exceptional to reach $10M, but you have to unbelievably exceptional to reach $100M whether you build a company that is a game changer in the industry (Amazon, Google, Oracle, Facebook etc), exceptional investor in the equities market (Buffet / Jim Rogers / George Soros), exceptional real estate investor developing in the path of progress (Donald Bren). 

In addition, household and personal income has been on the decline for years and is not keeping up with inflation in major factors of the economy, such as groceries, health costs, insurance, taxes, etc.Some of the old pros are already noticing a new real estate bubble being created on top of the existing one that is still settling.
