The interest rate on a HELOC or Heloan may be better than the personal loan. 

Point noted about not being able to underwrite without seeing things in person.

Remember that for most owners, their business is very personal to them.

I 100% agree with the intent aspect and that is an important premise, but the fact is in this particular situation intent for it to be personal use has been confirmed (by way of a public post).

While Facebook Marketplace isn't the sketchiest site (craigslist), I personally would never give my ID across it.

@Brice Alef-TorrisiHaving one checking account per property is an excellent way to keep your property finances separate from one another and your personal finances.

Quote from @John Friendas Quote from @Patrick Roberts: If you are on the note or personally guarantee the debt, then it will affect the liability side of DTI, regardless of whether the lender reports the loan on your personal credit.

The property is insured on your behalf, personally. 

Over the years I've noticed that it's very helpful to simply go visit in person your city of interest to get a better understanding of the market and the people that live there. 

The key is to identify personal property from real property.
