This deal leveraged strategic financing, value-add renovations, and market knowledge to deliver a strong return.

We’re working in a smaller market like Cornelia, GA, where comparable sales data can be limited, and want to make sure we present a strong case to lenders.

I'm not sure why not - one of the great parts about real estate investing is that you can build a team around you for aspects you aren't as strong at or simply want to delegate to someone/expert and do the others yourself - look up "Core 4" for example - where you can have an agent, lender, manager, contractor all at once for your investments and can theoretically just let them do all the interactive work

I can tell from your questions that you are in a bit over your head and before you make an incorrect decision you should STRONGLY consider a consultation with someone.

The Main St property in Grainfield, KS, offered a promising opportunity due to its low purchase price and strong potential for a high return after renovations.

It is entirely possible to self-manage with a strong cleaning team.

Another important thing to keep in mind is that markets with strong cashflow won't typically have as much appreciation.

Boston in particular is a strong market with great appreciation, a great tenant pool, and rents being as insane as they are it's nearly impossible not to pay less when you house hack vs. rent. 

I’m reaching out with an investment opportunity in a real estate flip project, and I’m currently seeking a limited partner to join me.With a strong track record of successful real estate investments, I am looking to partner with someone who shares an interest in capitalizing on the potential of this market.

i say that not to discourage you, but so that you have a realistic picture of what to expect.as @Travis Timmons alluded to, you need to be in a strong financial position to even think about starting to invest.
