Dark brown floors, white counter/cabinetry.I'm wondering if anyone has any good tips on how to take the pics, how to angle the camera, what modes to set them to, etc, and any computer software or websites I can use to edit, tweak, and enhance the photos to make them look spectacular.  

I like to run both and have both sets of numbers work (one for plan A and one for plan B), combine them both in an IRR analysis and tweak parameters to optimize the strategy.

The approach makes sense - I wonder if it could be tweaked in a way to make it more efficient....

Once you identify your end game, then you can make short term and long term goals to achieve it, re-evaluating and tweaking along the way.

Brought up to market rents and a few tweaks, I'm confident the building (at full occupancy) can realistically net ~$2,500/month plus or minus depending on repairs and maintenance.What do you think? 

Maybe, in trying to to determine the missed cash flow, we’ll need to tweak how we account for property management as they did this.

I have some things I need to tweak.

Maybe get rid of the 10% buffer if you already have a lot of science behind the estimate.Maintenance - As others have said, the maintenance number is too low (especially for 100% turnover) but your combined maintenance and cap ex do not appear too low.Appreciation and Principal Reduction - Cash flow is one of three profit drivers in real estate and to calculate the true return, factor in the other two drivers using the IRR.At a 60% expense rate for a $1450 rental, you are likely forecasting expenses a little on the high side (even with the higher taxes) but you may not be too far off (and the tweaks I mentioned may help).

and the Ask her how does she feels about it.. what are her thoughts ( even though you known) but still hear her out and understand. and tweak and modify and persist,  sometimes is not even  about RE.

(exit strategy is very important and "I" made it worked in my favor)So my 2 cents "Diversify" - bottom line is these are all vehicles which would create wealth for you in long run. tweak them as you learn day by day. and finally - be very aggressive and make every dollar work for you!!
