I have experienced unknown persons looking in the windows overnight with flashlights and scaring the other residents, etc. 

I think the biggest risks are the unknowns that can and will pop up and eat away at your cashflow and income.Also lack of experience, there are just some things that reading and school CANNOT teach you and the only way you learn is my experience.HOpe I am not scaring anyone but I think most here will agree experience is the BEST teacher here!

Stay put another year to qualify for tax exemptions but risk the value going down and the unknown conditions a year from now?

I just sold some land I own that, while doing their do Dillinger the buyer and I discovered an unknown under ground steam that was flooding a large portion of the property rendering over half the property unbuildable, with a very costly remedial procedure.

It’s hard to find an investment that returns a better ROI than House Hacking (even if cashflow is negative).There are so many unknowns when buying a house in any market cycle.

But it often masks a fear of failure, risk, and the unknown.

Sometimes it is easier to say no then wind up wasting time with an unknown client.

You will recoup the cost by presenting a nice property, capturing quality tenants that make the house their home and stay for a while.Some unknowns I have to mention would be, not clear how much you bought the home for, how much value you need to add, area/address ...... many unknowns also ... perhaps some areas will command a garage space more than others etc...It will only continue to get worst --- salvage what you can I suppose ---- the surrounding concrete may not be able to be saved if it is cracking, most concrete guys and driveway contractors will not tie into broken cement just FYI -----Feel free to PM me for more information #CLE#TeamTurnkey

The unknown is, will they survive?

Through our encounters with the unknown, we can grow and change, creating new possibilities for the future."
