@Derrick Wallace multifamily basics are very similar to any other real estate basics:You make your money when you buy - value add play and below market prices will help reduce the risk. 

. $100K in equity valued at 10% is worth $833/month and is therefor reducing the cash flow from the property by $833/month.

In that effort, hopefully, you can reduce expenses and enlarge your income.  

Your tenant will pay a bulk of your mortgage so you can justify a higher priced property initially.

I would low ball the bank as they have already reduced the price once and it has been on the market a long time.199 Commack Rd, Deer Park, NY 11729

Makes things so much better when everyone understands and agrees, and significantly reduces liabilities... 

I've been looking at places like Lowes & Home Depot, and the prices seem reasonable enough, but having never bought stuff like this in bulk I was wondering if there were better places to look?
