They charged a flat fee of $35. 

1st of all corporations own less than 2% of single family homes, they have actually reduced thier share of buying recently, now investors continue to buy up properties, it’s just more mom & pop types, all that said the housing market is in an extremely strange place, I could make strong arguments for prices pulling back, reaccelarting, or being basically flat, the biggest thing I’d advise is looking at you payment, comparing that to what would pay in rent, figuring out how long you plan to be the house and making an decision based on that, generally in that under 400k price point, breakeven for buying a property seems to about 3-5 years if you plan to stay in the house longer than that, bite the bullet & buy, if not rent.  

So they are triple dipping in profit on your deal -- they typically bake in the incentive (whether it's a $5k incentive or a $30k incentive) into the sales price.

And fast.You are flat out being misled if you do not think there is any risk associated with investing in real estate.Like any investment, real estate can go up or down.

Your NOI even for single-family properties is flat or falling because of the high supply and continually rising expenses (especially insurance, labor, and interest rates but those seemed to have plateaued).

You know it’s funny back when I was flipping in dc pre covid, I was always amazed at the prices and in the back of my head was like I cannot believe people are paying 800-1 million to be in a tiny rowhome in a frankly pretty rough area, now of course everyone who didn’t grow up here throught it was just was the way it was, but growing up here I tried to explain to everyone just how bizzare it was that the city was so much more than then the burbs, (from 06 on there were entire areas that went up fourfold, where as the burbs were kind of flat for a decade) I won’t say I saw dc’s crash coming but it seemed so unnatural to me having grown up in the area, I also don’t think we’ve seen close to the bottom as far as urban real estate, as you said you can still trade a house in the city for one in the burbs but really given how urban living is + remote works, cities should be significantly less than an equivalent burb.

He asked the right questions and I could tell he was serious, so I decided to team up with him, and we purchased this run down three flat, and gut renovated the bottom unit, while increasing the rent on the top two units.

Flat bonus?

And you're flat wrong about other things.
