In my opinion, the short answer is to use your cash and refinance it into a 'standard' loan if you are going to rent it or sell it when you are done. 

I can give you an example in my market here in Cbus for SFH 1,200 sqft:Roof - $7k to $9k Siding - $9k Windows - $450/window labor + material Flooring - $5/sqft Paint - $3k to $4kStandard Kitchen - $7k Standard bathroom - $5k This is just a general idea from what I am seeing. 

Bloomfield does have high rents however there a pockets that are still not up to the standard yet.

Since this is a capital improvement, it doesn't follow the same rules as a standard expense, so you'd likely start depreciation in 2023.

Thank you, Yes, the video is 4K quality not 4K.

Labor should run no more than about $1200, maybe $1500.A better quality video is really needed.

Talk to your preferred lenders about whether they see a cash our re-fi as being approved with the same standards as an investment, i.e. loan to value, debt coverage ratio, etc.

Of course your/my mileage may vary - but this seems such a standard thing to do, I can not imagine it's worth thousand dollars of contract rocket science.  

I'd like to find out what a somewhat standard practice out there looks like.

Simplify as many standard processes such as online rent payment, leases, apartment turns, paint, and other materials, and re-key all locks to a master system.
