Amazon never sold all those items at first.

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).

In my case I sold off appreciated properties in a location I deemed as having limited future upside, and used the proceeds to eliminate all debt on the better located prime properties I wanted to keep long term.

I sold this 30k property for 125k and bought a duplex.

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

I assume your question means you already have a 600k property that you owe 420k on, and are wondering if you sold that property to buy more properties which way would you come out better over time. 

There was a recent webinar, bottom line, it looks like Darryl Heller sold off many of the ATMs, didn't pay the people who put the cash in them, didn't pay the stores that have them on site, isn't providing information to David Zook's team that the court has ordered and is racking up something like $50k+ a day for not doing so...it is a complete mess and seems like there are only a fraction of the ATMs that might still be producing money but the company hired by Zook to get their hands around all of this is running into many roadblocks because Heller's team isn't providing info. 

Purchase price: $28,500 Cash invested: $28,500 Sale price: $80,000 Bought and sold a 3b/1b SFR with Owner Financing.

Can be a great negotiation tool.
