In these instances, you'd have to check things like flooring, plumbing for leaks, roof for leaks, hot water heater, and heating and air conditioning units. 

I think BRRRR can still work really well under 2 conditions: 1) you have another substantial source of income and your capital is somewhat renewable (I don't) or 2) you're willing to compromise on your target areas and move to secondary, tertiary, or out of state markets (I am not) or 3)  you're very lucky and/or skilled at acquisitions (I am from time to time).  

You can identify the hotspots for crime, school levels, income levels, where there is dilapidated homes, then based on the age and condition of the property gauge where the property stands in class, happy to talk further. 

Getting them to pony up even when they are at fault is impossible.2) This condition existed when you purchased.

Do market conditions, taxes, or potential rental income play a big role for you?

You know you already have or can find a buyer for this very same property in it's very same condition for $150,000.

I would explain to them that for the unit in the condition it is in now that the rent is still below market rate. 2.

All the replies above are based on ASSUMPTIONS about the condition of the plumbing.Is the plumbing able to handle the “standard” amount of toilet paper being flushed and the tenants are just “loading it up” before flushing thereby causing the problem?  

And, if you are buying a property that is already in good condition, or is fairly easily to rehab, you’re probably right.  

I am unsure of the circumstances, price, owner interaction, condition, but in the current market it is taking about 2 months from vacancy to move in.
