Normally when you hear cap rates this high the expenses are not calculated correctly or certain expenses are omitted (no vacancy loss, no management fee, light on repairs etc). 

That at least allows me to do some rudimentary calculations on tax implications.

Considering that DSCR  = NOI / Debt Service and NOI = Gross income less operating expensesWhen institutions are looking at operating expenses for a new purchase, how are they calculated?  

We also don't know the exact numbers of your prospective rental investment (including taxes, insurance, PM fees, etc.).Once you know all of those things, calculating this shouldn't be a huge task.If I had to ballpark it you'd be cash flowing perhaps $800-$1,000/month on the duplex given the rental amounts you ball parked.

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.

I've ran about 30 properties through the BP rental calculator, even if i renovate the basements I'm always coming up 400-1000 dollars short of breaking even.

Hey all, I am really trying to hone in on calculating ARV's in my area.

I want to feel more confident in my numbers and wanted to check with everyone and ask what strategies and software you use for calculating ARV based off of comps.

It automatically handles all the initial calculations for listings within 50 miles and updates daily.I'd love to hear your thoughts and any suggestions you might have.

From my experience too many investors are going the ground up construction and they don't often calculate all of the costs.
