I personally would go that route as it would probably be less expensive. 

My conversion rate was higher because they kind of look like a wedding invite.In regard to lenders, join meetups and local facebook groups and ask for referrals.I’m doing larger commercial deals now and found I wasted a Ton of money on direct mail.

For example, they won't need to cover your personal belongings (furniture, clothing, etc.) because you won't be living there.A landlord policy should cost about the same as a homeowner's policy; it just changes what is covered.

Did your borrowers mention securing your investment with a recorded mortgage or deed of trust, personal guarantees, lender’s title insurance, or anything else?

I’d suggest negotiating the furniture into the sale and then slowly swapping pieces later as you personalize the space.

But I just want to start the conversation so we can negotiate the terms so it's beneficial for both parties.

Also, would this loan help build my personal credit, or would it only report to business credit bureaus under my LLC?

House hacking is the BEST way to get into real estate investing and that's how I personally got started as well too.

I would build a relationship with the person before you decide to partner.

there's people out there who will fund downpayments for equity in the deal or a preferred return. hit up local meetups and facebook groups and have some conversations
