This will give you a great starting point in determining rent for your underwriting! 

The science part is determining where market cap rates are today. 

And you can determine the sweet spot for pricing your place based on comparable properties that are your competition."

Lease Terms: Determine a monthly rent payment that covers the HELOC repayment (interest and principal) while providing some positive cash flow for you.                    

Depending on the value at the time of death and your basis you may need to file a gift tax return.I would speak with a CA attorney to determine the best type of deed to file and a tax professional to gather more information.

@Polat CaglayanI've never seen a formula but here is a general rule of thumb for multifamily:The class of an apartment refers to the quality of the building, which can be determined by a number of factors, including age, location, and condition: Class A: These are the highest quality apartments, typically built within the last 15 years.

If that is all ok then get a very good local realtor to run comps in that area to determine the conservative value of the home once you've completed the renovation work(ARV).

And how do you determine your company's returns on these types of projects?
