I have used the BiggerPockets BRRRR analysis tool, but not sure if I have used the correct assumptions.Property:  1241 W CHew, Allentown City PA, 18102 (2-unit house)- listed for $73k- Offer: $40k- Closing cost: $9k- Repairs: $16k- ARV: $90k- Rent: $1,800 a month- Vacancy, Maintenance, CapEx: 10% each- Water and Sewer: $100 a month- Insurance: $100 a month- Property management: $180 a month- Property tax: $261 a monthThis leaves me $232 cash flow per month if I refinance it at $90k at 5% interest rate.

If the unit is empty, they will either use 75% of the standard HUD amount for your area or come up with a number from an appraiser.  

(We use the documents from legal blanks, they have standard blanked language for these issues).Hope this helps - good luck!

Plug in property taxes and insurance.  

It should work with the caveat that you stay away from the standard tiles that are made of pressed cardboard or whatever it is.

Everything I've been reading leans towards an LLC because there's more flexibility, etc. if I even need liability protection outside of good liability insurance. 

@Melissa Rivera Not necessarily but lending to a corporation is standard practice.  

We were supposed to close Sept 7th but the buyers’ insurance and Title Company put the brakes on the sale until after Irma passes.

What im looking for is an industry standard or guide for multi family unit's net profit after all expenses including debt services.

The $990 is including all insurance and taxes correct?
