Each parcel can host up to two units, effectively enabling up to four units on what was previously a single-family lot.

@Peter Mckernan Love the way you did that deal and agree that those deals exist both on market and off market you just have to be able to look for them in an effective way and add creativity. 

Once you have the number of homes you want, you pour your cash flow and extra income into the smallest mortgage until it is paid off, then you move to the next and create a snowball effect.

Dynamic pricing tools like PriceLabs or Beyond Pricing can help boost your revenue by adjusting rates based on demand.

The effect of this process is that the portfolio is constantly improving by retaining the best properties and jetison the under performers.I've bought and sold over 1,000 properties, and people always ask me "How many doors?" 

Tons of double sided tape used which results in a fair amount of extra effort to restore (most cases paint comes right off the wall requiring patching sanding etc, some cases Good-off was effective.

When I used the Insight Property tool on BP it had the median rent at $2500 per unit. 

I plan on doing most the renovations myself which requires equipment (such as tools).

You should also be well versed in the local vacancy rates and how they effect your unit and turnover times. 

LMK if you need any help accessing those tools on BiggerPockets.
