I've hit it where I've given myself an almost 8 week interest free loan before and had no utilization reported, which is awesome when you're knee deep in several rehabs. 

And unless you have very deep pockets, you can't afford to be that much off....So as has been said....hire a very experienced General Contractor and have them give you a budget number based on your SOW, (plus they will find other things that need to be done that you will not have seen).On your succeeding projects, you do a budget yourseld first, then hire the GC and compare numbers.Then, eventually you will be comfortable going all solo...but it takes time.

Then find matches for that product that you are able to buy at a discount. 

Its probably best to proceed with two separate DSCR cash out refinance with one broker who can get you lender discounts.

The other option would be diving deep with a bookkeeper to have them help run more updated books than just monthly.

I am making an offer soon that I hope is similar (near retail at slight discount rate) that is class A unit in a vacation market.  

Take a deep breath! 

Our pockets are not deep but we have full ownership of the land. 

But they are fairly deep scratches.

Obviously it is neighborhood specific but for me and every ADU client that I have where they rented both the house and ADU, they never gave a discount for the main house.
