When you get an inspection report if you're not aware of those sorts of things or if you don't have someone guiding you that's aware of that sort of stuff you'll probably just get scared off.

Keeping this stuff separate makes it easier to differentiate between my W2 and personal home expenses and my investing expenses.

Going to Home Depot to price materials, and calling local contractors to get quotes on some of this stuff, is definitely your best option.

Now, that may be cheaper in the long run because you're not paying interest on stuff like roofing, BUT it's incredibly hard to know exactly what one-time fees are going to pop up and when.

We're monitoring the feedback and discussing internally.

That gives you 60 extra weekdays to get up to speed on stuff that requires a lot of uninterrupted brain power.

The awesome thing about a lot of these tech-front-end companies that handle a lot of stuff for you on the back-end is that they tend to be out-of-touch in their local markets in terms of pricing and vendors. 

Do them a few at a time.I use a combo of common sense (for short stuff) and IRS rules (for stuff that's basically part of the house, like those kinds of flooring, roofing, siding, windows, etc.) 

Whoever was telling you this stuff is completely wrong. 

Before you do that, make sure you know your stuff inside and out, backward and forward.
