Costs are very high, but uncovered spaces aren't renting for that much (we're a frequent visitor to New Smryna Beach btw). 

Shingle manufacturers change their colors every 5-8yrs, so you should be able to find the same matching shingle and blend it into the existing. 

I would love to find 15 because if the special wheated blend.   

One of the best tools out there is a blended rate calculator that can help you determine if HELOC or cashout makes more sense. 

What questions or areas of the lender:client relationship should a REI investigate when shopping for lenders to uncover the value that lender offers as compared to others? 

If you were and lose the value of the rental, then subtract the rental amount from the total price to arrive at the reduced value to you.Are you asking HOW to negotiate a lower price based on this uncovered information concerning the property condition?  

HELOANS are an option, but you have to calculate your blended rate and compare that to a new first lien.

The answer is obvious to me, but please do other research or DM me and I'm happy to send you a ton of resources.Detroit is the kind of market you want to be uncovering today.

You uncovered issues and need to feel good about what you are taking on.

The disadvantage is that the indoor units are a bit large but if you place them nicely they'll blend in to any room.Another advantage is the upfront costs are much less than a traditional AC system.
