If you have a good plumber, electrician and appliance guy in the area you can handle most reparirs through them.If you must hire a property manager, I would get lots of referrals and check them out very thoroughly.  

An electrician we hired saved us time and money with helpful advice before we hired him.

Ask your realtor if they know of a good contractor who you can pay to do a walk through or a plumber and electrician.

The electrician that inspected explained to me that there was some cloth wiring present, but it was all grounded, making it safe.

So, whether it's an electrician, plumber, title company, or property manager - let's get this answer from other investors in your market. 

I spent the last 10+ years as a master electrician & running a business.

There are some avenues that you could use, like no tax deduction piece work job (still you need to pay taxes and wc).LOL, no, here are my WC rates, carpenter 50%, plumber/electrician < 10%, painter/drywall 20%, roofer 100%, plus/minus 3% on all of them and then a premium deposit of more or less $10,000/year, I have a self-performing sub (only works by himself + 2 guys) and said he is paying about $4,000 for a $40,000 gross payroll.

Run  some 220V wiring in pvc underground (licensed electrician) to power a good pump if you have space/amperage reserve in your electrical panel. 220V requires less current to run than a 120V for the same power, so it's more efficient.This guy has a lot of good videos on diy yard drainage systems.

So working with an experienced electrician, I purchased for around $500  the materials required and permit. 

When I was a newbie the inspection in a 6500Sq ft house showed K&T in the attic and because I didn’t know better I trusted when the electrician told me the whole house had to be rewired.
