@Choon Yee DeeRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

If anyone has any good leads on businesses they recommend for the fence (temp fence with windscreen bc its Chicago, sandbags) and porta-potty, please feel free to share your sources.

The cost of land generally includes the cost of clearing, grading, planting, and landscaping.Land preparation costs, such as landscaping are depreciable Certain improvements made directly to land or added to it (such as shrubbery, fences, roads, sidewalks, and bridges) are generally depreciated over 15 yearsKeep in mind that depreciable rental property costs with a useful life of 20 year or less may be eligible for bonus depreciation.I don’t think the sources that you found are accurate since some of the improvements you mentioned can be depreciated and over a shorter period of time.

There is no scenario that you hit $17,000 unless the oil has hit a movable source like water or has contaminated a neighbor's property.

There is no database or online source of this information.

Can you also give me all your referral sources that you've taken years to find & vett, so I can pester them with a bunch of senseless questions and waste their time looking at properties I'll never buy?

That is ludicrous.Them: Why would we continue to source deals from the MLS if no one was buying them?

Does any have a source or an outline of steps needed to be taken?

Now is a good time to start networking with wholesalers and learning how to source off market deals.
