Personally, I'd angle for a 4plex or triplex so that you can get a larger conventional loan at the current great rates.If you're shooting for 1M/year in SFR... and you make $1,500/month/house, that's only 55 houses.... not that unreasonable. 

Our loan paperwork specifically says that consent shall not be unreasonably withheld.

Prices are unreasonably high, I just don't understand how people afford buying as everything in near the unaffordability-level.

$4.74/ square foot or $474 / square is not unreasonable for a flat roof. you may be able to find someone for less, but that is an average price.

So if you think that rates will increase (not an unreasonable posit) your locked rate will take you though the next 2-3 cycles.

In my state, if fees are considered unreasonable or one-sided, they are simply tossed out in court.

I can promise you that they are not allowed to keep it for any unreasonable period of time.  

The 2,500 fee for a small loan for a mortgage broker is not unreasonable.

A house with no equity doesn't necessarily indicate a house with an unreasonable monthly payment.

I think it's unreasonable to expect agents to do more than list and maybe find buyer.
