I learned that it's better to go for quality the first time if you want it to last.Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Milton and Farmington can be excellent choices, too, often with more budget-friendly options and the chance to add value in less saturated areas, might have better cash flow luck here.For lenders and agents, I'd recommend networking with those who have experience specifically in the NH Seacoast markets since these towns can vary in terms of tenant demographics and rental demands.

According to the brokerage and agent, these individuals either weren’t serious or claimed they didn’t realize the property was occupied, even though it was clearly stated in the listing.I’m not particularly concerned about the property’s condition or the eviction process, as I’ve already secured some level of cooperation and have basic access to the basement.

I recommend you contact a residential banker and a commercial real estate agent and start looking at deals right now, even before you are ready to buy.

Utilize Meetup.com or Eventbrite for real estate investing groups, BiggerPockets forums, CTPOA, and local events to connect with landlords, agents, and property managers.

I have 5 years of real estate agent in Central Indiana.

I didn't get an LLC but got an umbrella policy and talked with my insurance agent about the amount of coverage on the home. 

@Tanya Maslach Since it sounds like you're not really using a property manager - connect with whoever helped you purchase the property to see if they know of a leasing agent or showing agent that you could reach out to help hold the property open to tour at least once to twice a week for an 1-2 hour period on weekends. 

Make sure your lender, agent, and real estate partners are all on the same page.
