It’s possible that he is just trying to teach me a lesson about how “not all deals should be pursued”, but I want to exhaust my options first.Thanks! 

Later, you'll exhaust that option and might have no choice but to get creative for financing.

I don't know if they are giving me quotes on economy of scale, but I have 100 squares, and the quotes have been around the $20K mark.  

A fan with the "exhaust setting". 

I'll try to think if there were any more differences, but these were the main ones.I'm a bit concerned about the impact of economy changes, but of course, there is a sales pitch around this.

I came across this article with lists of fastest growing and declining cities in the US https://www.usatoday.com/story/money/economy/2018/05/26/fastest-growing-and-shrinking-us-cities/34813515/Since I’m interested in East coast only here are my best bets for MFR rentals.

WSJ post article titled: "Housing Market is Faltering and Strong Economy Offers No Cure". 

We typically do $50-$200mm deals and a lot of times during diligence there’s a third party analysis done that will review the Company’s insurance policies to see if they are adequately covered across the board.In regard to the closing costs, I reference the below link just as an exhaustive list for one property.

For the $900 we’d gross, it doesn’t make sense to tie up the $360K in equity.Frankly, this economy has me questioning if I want to wait for the next downturn to invest as interest rates are nearing 5% and property values are beginning to stagnate as we approach our 10th year of economic growth.

Traditionally I have read seller financing is geared towards buyers that may have exhausted the amount of loans they can get, maybe there is a lack of credit history or maybe they have a less than desirable credit history etc...
