I am estimating at least $50,000 between furnishing it and updating.How does this look:$1.3 million with 20% down DSCR loan buy-down the rate from 9% to 8% 30 year = $9,332 (principal/interest/tax).Utilities - $750Income - Was thinking $250 per day but let's say $225 per day for each unit (30 days) just looked at AirBNB and AirDNA in area = $13,500 (.20 vacancy) = $10,800.I would manage it, but still need to think of cleaning fees.

I spent considerable time pulling comps and estimating fair market value, but given the unique features of this property, it was challenging to reach a confident valuation.

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.

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.

In my estimation, somewhere between 20-100% more.

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

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

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.

Who walked it for you and provided the reno estimate? 

With an estimate in for the roof ($10,000 approximately).
