If the repair process requires painting the whole thing, which it may need to look good- I'd optimistically put the lifespan of a professional/specialized 2-part (epoxy or urethane) tub/surround (or tile paint) etc- paint job, with above average prep work at ~3 years.. a "high quality" tub respray like this will cost just as much as a brand new tub, and touching up/blending a spot repair is specialized, expensive work as well. but yes I agree with the other replies either way -(unless, *perhaps* there is already easy access from behind etc to get to the repairs and inspect flooring etc without taking tub out)- it makes sense to rip it all out so you can address any potential water damage, and overall there is no reason the resulting new unit shouldn't cost aprox the same ballpark as the repairs .. and new of course will look much better with a much longer lifespan. 

I am sacrificing some return to fully automate my facility with just maintenance staff we are closing in January and am coming in with 10 percent down.

Once you have that figure, estimate the monthly payment and potential rental income to calculate your DSCR ratio, ensuring it meets your lender's requirements.

If this is a brand new facility no matter what, you will still need a Certificate of Occupancy if that PZ entity requires.

DSCR loans have become extremely popular amongst foreign national investors because they do not require income verification to qualify or U.S. credit history (many use local credit history from their home country to verify creditworthiness), allowing for a more efficient underwriting process.  2.

Question:Is there a permitting rule that requires a 7 day stay and only checking in on Saturday?

Most investor products are going to require anywhere from 15-25% down for eligibility. 

I only have 9 units and see some require 500+ units to participate. 

Does the company have a maintenance person that will handle small repairs or will you become responsible for every hole punched in a wall or other thing that gets broken and damaged.
