Remember, you can always ask for concessions and additional discounts once you're under contract and have your DD period for inspections.

Additionally, is it ethical to advertise discounted rent for specific businesses (IE. $1 per sqft for generic office space, but $.75 a sqft for those specific businesses)?

But I offer contractors service at a discount, top quality, dependable, etc. and I am partnered with a few money partners.

Hello:I am new to this website and also to real estate investing.Are you aware of any software or tools that can scan/identify properties selling at a discount to the market value or that has the potential to generate positive cash flow in the long term?

And the mortgage discount depends on tenants credit.

Also, you can't discount someone just from what they look like - make sure you are educated about the Fair Housing Act!

All PMs also have RE licenses and sometimes represent their clients on the sell-side - you may be able to pick up units or even whole portfolios that wayI'd not discount wholesalers, but as mentioned earlier, you need to know what you're doing there.

Or, you'll have to discount a bit (not sure how much).

A $400,000 fourplex with 5% downpayment owner occupied with Freddie is at 4% on a 30 y fix, no origination or discount points and as investment with 25% downpayment is 5.125% on 30 y fix no origination or discount. 

Therefore so long as the seller as sufficient funds from the sale he/she can sell the property for much less, typically 50% of the appraised value, leaving sufficient equity for you to wholesale with a profit and sell to a buyer at a discount.
