I am torn between paying $15k or $100 per call or $39 a month for a bigger pockets membership.Well, I'm not totally torn because my wife made the decision for me. 

For me I would take $250 per unit monthly cash flow all day every day.  

There’s a duplex for sale by me that’s on realtor for $609K it’s 2 bed 1 bath per unit. 1500 st ft.

there is value add for sure but they are all small apartments so won’t increase drastically looking at $50 per apt prprobably at most in the near future.

I'm not familiar with Maricopa, Arizona and unsure how competitive it is, but I don't think your cost per deal should be $10k or more in this market.

@Lee Underhill if you can buy $80k condos, with reasonable association fees, and rent them for nearly $2k per month, buy every one you find!

If I'm using traditional model for 1-3 units and outsourcing management at 10%, after collecting rent (let's say $1,000 per month per unit), mortgage, taxes, insurance, vacancy, maintenance and management, I should be able to cash flow around $300 depending on taxes at 100% occupancy.

Briana, unless you can get more per door, I would not do it.

2024 is 6 years awayI plan to spend the next 6-12 months learning and studying dealsI estimate that in order to replace ~$130,000 of gross annual income I will need to have that same total of net cash flow from my properties by that time (I currently only own two single family houses)If I make the assumption that the deals that I find/buy return $500 per month of net cash flow then I will need a total of 22 properties to equal $132,000 per year (22 * $500 = $11,000/mo. * 12mos = $132,000/yr)The $500 per unit estimate is not a per door estimate, rather a per unit estimate.

This is varies per location.
