4-Plex details: -currently occupied-estimated sale price 265k-ARV 400k, and 4k/mth in rentBackground on me: -I have an LLC-I own 4 single family rentals-each has around 70k + in equity-all cash flow well -credit is 800+ with adequate income.

I would appreciate any knowledge share, or tips and advice on where to gather information to properly estimate for such a project. 

Who walked it for you and provided the reno estimate? 

The difference in build cost could add or subtract sqft but more of a quick estimate 

They will run your credit anyway later, but the bank can give you some estimates with the credit score.

Rehab costs that are under estimated by very wide margins.  

There are a few items I have no idea about, I'm hoping someone here has some experience in the field and can provide a ball park means of estimate 3 costs:1.

What I really look for in a agent is can they confirm or deny my ARV and rent estimate and explain why.

I'm just north of the lake, thinking of doing the same, have about the same equity, and my estimates ($3500/mo) seem to cashflow a couple hundred a month.

I got several estimates from roofers and the replacement cost is around 13k (it's a ~1600 sqft house).
