No one has given a quote to just repair it, as they’re not guaranteeing that it can be fixed, since the burn marks are deep.Also for sanding it, I was told they will have to remove it and the backsplash tiles could be damaged.

I am no expert but some issues you might want to look out for:- Mold in crawlspace/basement (as well as evidence of running water during storms, we've seen this)- Structural damage/settling (definitely hire an expert on this one)-Improved Electrical/Plumbing (These systems DO have a lifespan and the older systems aren't as reliable as newer ones)- Asbestos Flooring and Tile (Where I am from the removal of this stuff is mandated by law to be done by a licensed professional, no DIY.

So, gonna do granite counters in kitchen and tile on bathroom wall,etc.How do I know how much of a loan to request?

Hi Rigo,If you are unsure what materials you are going to be using you can have the contractor exclude the 'finish materials' (tile, paint, plumbing fixtures, light fixtures) and include just the 'rough materials' (studs, drywall, wiring, piping, etc.) and installation of the 'finish materials'.In this scenario, you will be responsible for purchasing and delivering all of the materials for the project, so it's added responsibility for you, but it will give you an opportunity to figure out what materials you are using on the project.I have a Scope of Work example in my file place which will show you the level of detail & verbiage you need to include in your SOW:https://www.biggerpockets.com/files/user/drobertson/file/sample-contractors-scope-of-work-documents

I only have current rental rates per unit, not a full T-12 (which I would anticipate would look worse, given the amount of vacancy that would be required to do the interior renovations that they have done (updated flooring, full paint, updated countertops and appliance, updated bath including new tile work and fixtures (except tubs). 

Going a little over the top in the bathroom could be a good strategy, it's low square footage so it won't break the bank if you use more expensive tiling or fixtures

It’s made of concrete, brick and tile and needs to be repaired before a sale.

Remove the fake tile in kitchen and put nice rectangular tiles.

And the downstairs has zero carpet  all tile flooring.

If the tile is a style I don’t like, but, it’s not chipped, I save it, etc etc… the trick for me is to start with all major mechanical items: hvac, HWT, panel, and then add the roof… if all that checks out then the odds of a minimal rehab are even better!!!
