Because of this difference, the approach the the business plan, financing, and other aspects of ownership are completely different.IMO, every commercial property should cashflow. 

I wouldn't even bother asking for comps or how much they think the repairs are, it doesn't matter what a wholesaler comes up with, a real buyer will know how to assess on their own how much the repairs will be and thus how much they can pay for the house depending on their business plan (either to fix up and rent out, or fix up and flip/sell). 

Another option is MightyCall—it's the best decision for small businesses.

I read over a sample personal umbrella insurance policy and it says that they dont cover injury due to business property, and that business property is defined as residential property rented, or held for rental, to others.

Giving the tenant a lease also allows you to impress upon the tenant that you handle your business not only by giving them the lease but also how you present yourself.

I have been growing the real estate sales side of my business over the last few years and am looking to spend a little bit more time on the investing side in the coming years. 

DSCR 1 ratio will get you best terms depending on your credit and LTV for many lenders who specialize in DSCR loan products which in many cases isn't banks or credit unions as they don't feel as comfortable with the products as conventional loan products. 

Once you get your systems down, you have a real estate business that you can take anywhere and be still be successful.

@Luis Valles I've added wholesaling mobile homes to my business, if you're interested.
