Questions like: how long their units have been vacant, do you or the residents pay utilities, how many tours have you been giving each week, how much is your application fee, etc.You can obviously customize the questions to fit your needs.

These include (but not limited to) mortgage payments, taxes, insurance, utilities, HOA fees, etc. that occur during the Rehab period and up until the property is fully rented.2. 

I also ask about the utilities and which are on separate meters.

I've seen a lot of marketing dollars pumped in and produce no deals so be careful with your plans.

As long as I’m in LA with decent Tenants paying the total mortgage and utilities I’m perfectly fine with anything I can get “easily.”

With rent at $800, expenses at 50% ($400), deduct the cash flow you are buying with your 40K ($330) and your positive cash flow produced by the property itself is only  $70/month.

It’s probably easier to just raise the rents to cover your utility costs or look into electric heat pumps.

Utilize your strength and go for it.

I'd just ask what condition the property is - if it's not turnkey then the 5% for capex, maintenance may be too low (and I agree with Cade that vacancy should be bumped up a bit too) - 8% is where I'd start with those three, being as conservative as I am.Who is paying utilities and associated costs? 

You don’t make enough money to pay someone to run it for you profitably, and if your not willing to put in the extra hours after work once you’ve acquired the unit to get it rent ready and producing, your just fooling yourself.
