I am finding conflicting info elsewhere online. 

@James Mays  Seems your objective is to scale your business.

I'm diving into QuickBooks Online for the first time and could use some guidance.

Making the connection in person is completely different from an online interaction.

Is there an online platform on which we can do this or do you track this in a excel sheet ? 

BP offers free online videos and educational courses for you to watch and learn from.

I am going to have my tenant pay rent online directly into my new checking account.

Online videos on social media platforms, educating your clients about nuances in private lending, coming on a popular blog to help people with financing issues, and connecting with others in your industry that specialize in something else. 

And, even if you could find an appraiser to do an evaluation, it's not clear how that would help you.As you state, the motel has been shut down for nearly three years, so there's no current financial data.But even if you had recent numbers, you're planning to operate it as a sober living facility, which I suspect is a very different business model.You need to find a comparable facility in or near your local market and develop your own customized financial analysis model based upon this particular property.Then, given your business objectives (cash flow and cash-on-cash return, I assume), you'll need to back into what purchase terms you'll need to achieve those objectives.Only then will you be able to determine whether these seller financing terms will work.As far as documentation to get started, a letter of intent (LOI) is commonly used but you might move straight to a purchase and sale agreement, particularly if no agent is involved.Whichever path you choose, just be certain to give yourself plenty of time to thoroughly perform your due-diligence.

To make sure the investment satisfies your financial objectives, establish your target profit margin.Decide how much money is needed overall for the transaction.
