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

Is there a place to find Private Investors as in one person?

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

I warn people over and over and over to know what they are buying and to go personally see what they are buying. 

@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.

So I wonder if I can sell my home in Idaho, purchase the new one under my personal name, then how many months or years must pass before I can setup an LLC as the owner of my primary residence, or if you think that will be a good idea? 

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

My guess is that it could be structed as one person handles everything locally 'boots-on-the-ground', and the other acts as the investor.Has anyone see or done deals like these?

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.
