I the understand the wiring for this specific purpose equipment can be considered with the tangible property. 

If that is the case then that is considered cost of doing business and I would advise that should be calculated in your costs/returns you provide to the investor.IF you are referring to the investor who is the borrower - then I would have included that cost in the loan agreement.

If communication is an issue, consider getting everything in writing or checking reviews for more feedback.

Consider partnering up with someone for your first deal. 

Also for me I do not consider this as investing in real estate.

Your suggestion would be considered a negative cash flow investment.

Dan, Investment HELOCS are extremely hard to achieve considering they are not DSCR underwrites. they are more traditional conventional qualifications.

DOM is useful in a micro sense, though, especially if you are considering whether or not to use a PM. 

If the property is not yet generating income, you might want to consider other financing options like renovation loans or bridge loans, then refinance into a DSCR loan once it's stabilized.Hope this helps!

I would consider staying with your parents and investing in another market that stretches your dollar and covers the cost of a professional property manager.
