You sound exhausted, discouraged, and mentally defeated.

Markets are no different than an individual property in manner that it must have more than 1 profit strategy.

If numbers are not accurate then results will not beBut what can be done is understand things like if rates go down is that more impactful than an increase in service fees?

I am so exhausted of the pity party on BP.

As to the OP question, if your vent line just connects to a wall mounted exhaust that empties directly outside at that point, then the vent line should have simply been replaced at the time of the equipment change-out.

He’s weighing putting his Orange County house on the market and becoming a renter rather than an owner.

That’s a lot more leverage than an eviction for gods sake.I have a lot of sympathy for the difficulties of your position but you took me aback when you seemed to be wavering and saying “oh man it would cost me so much with them not paying rent” and it seemed like you were thinking of keeping them.

As much as "happy" they can be anyway.The thing to be very careful about is on the loan application it asks if you will be living in the property because an "owner occupied" interest rate is lower than an "investment" interest rate and they underwrite the loan accordingly. 

Exhaust the free resources, figure out what kind of strategy you want to use, a market, etc. and go from there.I will say, I probably wouldn't sell the stocks to invest in real estate.

my point of view is that depends on the area. if you over budget on a neighborhood that cares more about how close the walmart is rather than an Italian hand crafted crown molding you will loose money.
