You will need a manager (you will have to find and hire them) that you can totally trust - you won't be there to check in, so they have to be honest, or you'll risk it all. 

If you don't have an accountant, you may want to hire one or atleast get one to give you a consultation.

You may want to hire someone to consult with to make sure you are doing everything correctly.The issues that I normally catch are people not properly allocating expenses to business and personal.For example, mortgage interest will likely be split between personal(part where you live) and business(area where tenant live).Furthermore, I often see people deducting the full mortgage payment when only the payment to mortgage interest / real estate taxes are deductible.best of luck!

Call as many phone numbers as you can get your hands on and hire based on vibe.

Renting our our carpet cleaner for the day may be best bet I have used rental cleaners (Rug Doctor), own my own cleaner (Bissell) and hire cleaners (steam van type).

Very time consuming unless you can afford to hire a bird dog or 2 to do it for you. 

Amazon just announced in July that they are building a $250M distribution center in Davenport and will be hiring 1000 employees so that is big.

They hire third party service providers with low negotiated prices.

i will hire out stuff like garage door springs, water line replacement, new roofs to name a few things.

If you are new to it, I won't say you need a buyer's agent, and I would highly recommend not just hiring any agent, but I would seek out someone with experience as an investor.
