This could cost around $500 to $1,500 per unit, depending on the size and complexity of the project.Certifications: There may be additional costs for certifications (such as HERS ratings) or third-party testing to verify the energy efficiency of each unit.For a 90-unit project, you could be looking at costs in the range of:$45,000 to $135,000 for energy modeling and certification (depending on the cost per unit).For a 112-unit project, the costs would likely be:$56,000 to $168,000 for similar services.Tax Credit Calculation:If you meet the energy standards, you can claim up to $2,000 per unit.

@Jaycee Greene Price range probably up to 350k ish 

-there is tremendous demand for inventory among both primary buyers and investors. 

Ranges can be fine if they’re in good condition, but inspect them thoroughly.

Multi family can range from about $60k-$125k/unit.

You can find something in Durham and parts of Raleigh, specifically zips 27610, 27603, and parts of 27604 that would meet your criteria, however generally speaking most of the inventory that would fit what you are looking for in Raleigh or Durham would likely be in neighborhoods that I personally wouldn't want to invest in, C- to D type neighborhoods.

What price range are you comfortable with?

Do you have a preferred type of property and price range you're looking for in general (knowing the costs can be different based on they market)?

I don't see much waterfront in that price range of 650k or under.

There is low inventory, lower sales volume, and high interest rates, and as a result many people are sitting on the sidelines, either intentionally or forced.
