I would appreciate any knowledge share, or tips and advice on where to gather information to properly estimate for such a project. 

This is my first extensively water damaged home that I may purchase. Surprisingly, it has nothing to do with the roof. The roof and attic are the best parts of the house, 0 problems.
Main line, laundry line, kitchen ...

@Josh CaughranWelcome to the community and be ready for a huge amount of information at your finger tips.

Any tips or resources are appreciated.

It does seem competitively priced for the area.If anyone has insights into how the existing HELOC might impact the mortgage assumption or tips for negotiating on a deal like this, I’d greatly appreciate it.

However, with the frequent incidents and the persistent odor, even after cleaning, I’m beginning to wonder if this has become the norm for STRs in urban areas.Any advice or tips on how to prevent this would be greatly appreciated!

Quote from @Gabriel Juarez: I’m turning 20, any tips for anything to do with real estate?

Anyone have tips for finding them and how to structure the deal to become lucrative for them as well?

Thanks for the tips @Mindy Nicol, I do think MTR would be easier to manage for me allthough I do have time for a part time job, I see where you are coming from with repair costs and all and STR sounds like it can be a pain (I followed a few groups on facebook and have read horror stories :D ). 

Great tip.
