It was costing me $450/mo plus a $90 subscription to quickbooks online.

You should be able to find one that can explain exactly how they will fix this, how long it will take, and what it will cost you.

Are you currently using house hacking as a method of investing, or are you using different methods?  

Honestly it’s all about opportunity cost.If that additional cost is going to yield you more than it costs; then pull the trigger .If you borrow a down payment, it’s going to reduce your cash on cash return as your mortgage payment is increased. 

How much legal $$$ could this cost you?

Cost wise they are all very comparable, maybe $5 difference per unit per month and in exchange you may have a little more or less features.They all have similar features (comparing the pro version).

People funding in 2nd position behind hard money at 75%+ CLTV on flips with aggressive ARV's, people funding EMDs and closing costs for "wholesalers" who have completed 1-2 deals and dont have $5k to their name, etc.

Quote from @Bruce Woodruff: So that's 7 months......now investors will have to add a bit into their flip budget to cover the extra 3 months (or so) holding costs... will make overall costs go up though... 

My concern for you is that it appears that if the owner comes back, they only have to pay the bid amount + costs, not what you paid for the broker.

I'd personally be a bit more conservative with the underwriting and make sure to see what the carrying costs could potential get to especially if this is a bigger renovation and not just cosmetic.
