Anything will chemicals, detergents, carpet, drape, new car seats can cause more health discomfort and Feds have not tackled them yet. 

After you pay closing costs from a sale, you would net around $60K which could be used to fund a down payment on the next house, or to even tackle some consumer debts and improve your cash-flow position. 

I haven't tackled it yet, but I'm going to try the wire wheel in my angle grinder and see how it goes.

There are mold remediators out there if you don't want to tackle it yourself.For a Live in Flip, keep your sanity by choosing one room to NOT work on, one place where you can get away from the dust and mess.And if you're living in the flip for the tax gains, do not sell even one day before those two years are up.

I am currently thinking of doing basic work such as floors, cabinets, tiling, and bathrooms so projects I believe I can tackle on my own.

Is this something a beginner should tackle?

I think @Mike Dymski has a good approach to it. and i would tackle the exterior and lobby first, first impression of the place is always key. as far as the distance, do you have any kids, relatives or friends that may want/ need a part time job ?

I structured this post by tackling the items based on who you are working with.Working with a Turnkey Provider-Make sure you do a thorough research when picking your turnkey provider.

.- Gas Boilers - 30+ Years Old- Hot Water Heaters - 10+ Years Old- Electric Panel - Upgraded within past 10 years but could be upgraded even more- Pipes are old, corroded, and some leak often- Windows/Doors that haven't been updated require much more labor to remove/replace as the wood is often rotted- Roof is old, has recent touch ups but will need a major repair down the road (10 years hopefully)- Interior is covered with old wall paper, most walls have multiple layers and are a PAIN to remove- Also, shag carpets were apparently a thing back in the day so get ready to rip those bad boys up and replace them or refinish the hardwood if possibleThere is much more of course but those are some that I definitely noticed right away and are what I plan on tackling, priority wiseAny questions let me know!

The value of a turnkey company is they do a majority of the legwork for you, so in theory that's either because your time is better spent doing something else or you lack the skill set/networking to tackle a project like that.If neither of these applies, then you're better off doing it yourself.
