There is no other investment vehicle that increases net worth and throws off cash quite like real estate. 

You could also simply give notice that at the end of their lease the rent will be increased by $1,000, which would probably have them move out anyway at the end of their lease.

Student housing is probably still a sound investment, just don’t expect the dramatic increases seen last year in students from India to happen every year. 

I know how buying a house for a primary residence can become an emotional decision which increases the amount a person is willing to pay... but with attempting to pick up a long-term buy and hold, at least in my experience, the profitably is largely determined at purchase (and of course subsequent to this, proper tenant screening and management of the property).

Therefore for apartments you want to strive for buying ones that you know you can increase the NOI of after you buy it (forced appreciation).

We are going to see less and less 0% interest options and more and more increases in interest rates. 

By the end of this assignment (I move again June 2021), I will have 3 properties netting ~$1700/mo.My question is, on my timeline I have another 14 years of active income to turn into passive income - should I start rolling my $1700/mo back into my mortgages to increase cash flow from rents, or should I focus all of my funds on acquiring new properties?
