Is renting by the room even after I leave sustainable?

If an area or state or even the US population continues to grow, well people need places to live and vacation, so to the extent that there is good demographics in an area and the sustainability of the income of the area, this will help dictate values and growth, or stability or decline.

Partner A: Owns and runs a business, has comfortable consistent cash flow to sustain estimated payments for such a property but minimal credit history. 

If I didn’t have the luxury of the income, it wouldn’t be sustainable, but with the physician income it’s something I think that is worth stomaching.I saw people saying I should invest in commercial for medicine or move to other types of investment.

Multifamily sellers and brokers are pushing that there is no vacancy, no deferred maintenance, and strong annual rent growth.Over the history of multifamily the rent growth being quoted and low vacancy is not sustainable.

ok. everyone uses their particular formula. my preferred is just gross income over purchase price.partly because some investors especially new str folks seem to not grasp the importance of buying low (auctions, foreclosure, etc) and finding the pockets and methods of sustainable high rents.people seem to not also include appreciation or loan payoff.

I need about $2000 CAD a month to sustain and pay all the big cost like strata fee, car related cost, food, etc...

But if you want this to be a sustainable "business", it requires a consistent flow of DEALS and deals require a consistent flow of LEADS.  

I'm a workaholic, and although my business is doing well, and I can bring in money for deals, I hope to be able to shift my focus to real estate to have more time with family, residual income, and a sustainable future.We have experience with renting, both good and bad. 

I’ve lived on my current budget for several years (essentially living like a grad student) and know my living situation is comfortable enough and paying this amount is sustainable for me.
