things to look for:Current rental demandCurrent rental supply - are they building more apt complexes/affordable housing? 

I'm working with a few people on multifamily... right now people are asking a bit too much... demand has dropped off a bit but supply hasnt yet taken the hint.

The supply and return plenums will likely need to be re-worked however if you can use the supply branches to the actual spaces, you could conceivably save a ton of money there. 

It is softening now but is still a seller's market with demand greatly exceeding supply in both rentals and single family.

My houses can rent for $150 more per month in June versus December, just due to supply and demand.

We cut the grass and found the house open in a few places so we went in and found building supplies etc but obviously no recent activity.

That's not a ton, compared to CA and NV and NY and FL, but it also doesn't lose much, if any, when things go south.Also we really don't have a ton of supply around here, as the big building uptick has been only fraction of what they used to be.  

So I read up on it , picked up misc supplies this morning .

I flip 10-15 properties a year and was wondering if i should hire an Electrcian that has a few trucks out there on the road and pay him monthly regardless if i can keep him busy all year. that way when its time to rehab a property he gets his guys over there and i just pay for the supplies. maybe 30-40k a year. probably 50-75 days a year. like a subscription. 

Planning should be like that.At the moment, depending on where you operate, inventory for updated homes tends to be in short supply, so it almost doesn't matter when you list.
