Ask your broker if the brokerage has a referral division and if there are any costs.

This could be less costly and smaller hurdles than you would have with hard money lenders.

I'm seeing somewhere between $50K-$75K when it cost double.2.

Are there risks or hidden costs I might not be considering?

You could also get a line of credit for about $150k (you should be able to borrow 75% of the value.)The reason I suggest this is…1) you save $40-$60k in selling costs. 2) you have a lower blended interest rate (2/3rds at 3.25% and 1/3rd at 7 or 8% instead of the whole $500k at 7 or 8%) saving you another $1k/mo in interest. 3) you only pay interest on that $150k when you actually use it, not from day 1  Unless you hate this property, or want to buy something you can’t afford without selling, that would be my plan.

Well anyone can write anything into a contract, but whether it is legal and enforceable is for the courts to decide...It is State law here that a contractor must call 811 or they are liable for the costs.

I’ve been thinking DSCR but don’t they typically have higher down payments and closing costs?

It is fair to express your disappointment that they exceeded the cost target you gave them. 

Many who want to scale  fail to take this into consideration,  take on too many projects at once, have no capital to advance the construction and ultimately get stuck in mud unable to advance any of their projects.
