Wanted to follow up here with where I ended up.
My purchase price was just under $300k, the house took 6 months to complete (2.5% deposit in Feb, closed August 10th). It appraised at $315k, there was strong tenant interest and I had a signed lease two weeks after listing. It's renting for $1950/month (includes lawn care).
Builder doesn't handle fencing at all (claimed due to the liability issues), didn't have to worry about a mailbox as it seems all new complexes in that area are required by the postal service to have centralized mail kiosks.
Blinds from the builder were pricey so I purchased 2" blinds for the whole house at Home Depot and coordinated a local installer to put them all in after closing, he did a great job. Builder appliances were priced about 1.5-2x market rate and were outdated two model years as well, so I purchased those out of pocket from Best Buy with free install. Financing them in would have been simpler, but apart from having to have the cash on hand it was pretty easy doing it afterwards.
My goal was to enter the market, get my feet wet while learning through the experience, and hopefully just not be in negative cash flow. So far so good.
