You have to define what we are talking about here.Average that I see is 30% Operating and Expenses,10% property management,10% vacancy.Every building is different and has it's own set of challenges.If someone self manages they can claim lower operating expenses with no management costs.Although the landlord does use up their time and energy which should have a monetary value to it.I tell landlords when I list their property that we have to count a property management fee in the numbers.If not a majority of the buyers will not be self managing and the numbers won't make sense to them.Otherwise we will be looking to sell to a small group who self manages.It depends on the size of the building as well.Many small buildings like a duplex or quad is self managed.Most larger buildings are not but there are a few.If you go over 50 units you can easily get a 5% property management fee but vacancy can generally run higher at 15% and with 30% O and E still puts you at 50%.I do see some buildings running at 60%.It's because the owners are underwater on the loans and have not maintained the property.They keep having to do patchwork repairs to get by and have high tenant turnover with rekey and reconditioning unit expenses which drives O and E above the 30% mark.If you factor rehab and going in and making changes and charging a slightly lower rent you can decrease tenant turnover and cute repairs to bring inline with the 50% total costs.You just have to look at what you can do with the property.The 50% is only a starting point.

great app...however, if the battery is dead, i'm assuming you're SOL, correct??

Now, we have enough batteries and chargers to make it not worth switching brands.If you decide to buy, look at the newer tool options where you can simply switch out the heads, and use a couple basic tool bodies.

I provide smoke detectors & change the batteries myself twice a year (that way I know it gets done).

Battery life isn't great.

Red hook is right on the water across from Manhattan through the battery tunnel and wow did that area change for the better, but where the projects are is still straight ghetto and might never change.

They have a battery powered red blinking light to make it seem legit.

@Tristian Cox, You should have a large emergency fund regardless of it being in a flood zone or not.Also, there are battery backup systems for the sump pumps.

Just make sure the timer batteries are changes out regularly.

Create a whole battery of these types of questions and take copious notes.
