Don’t put every spare dollar you have in real estate and always leave some aside for capital expenditures.

So now I have three rental units, plus I also rent out a spare room in my personal residence.

A stationary bike is compact enough to fit anywhere!

I hope I'll have a service robot like figure1 to help me when the time comes to spare me the humiliation.

I hope this helps and I was happy to hear that your properties were spared from the recent fires. 

No reason to hurt your margins if you can spare the time. 

Once you have enough cash to sparingly invest in different projects, put some in rentals, use the other to make more.If real estate investing is your long term.

However, if you could spare some time to review my analysis and offer your expert feedback, it would be immensely beneficial in shaping my path forward.Thanks!

I bought my first duplex in unlivable condition for $45K cash on the barrelhead, spent three years of my spare time making the upstairs a nice apartment and the downstairs liveable on a shoestring budget.

It does not seem house hacking is possible in this market without renting out spare bed rooms (which is not an option).
