Not so important for an opportunity zone although there are some tax deferral benefits available with those.The only advantage I can easily see is that the LLC itself has value. 

@Jay Hinrichs there is value add in every market but unlike yesteryear when value add meant buying at half of rebuild cost and pushing rents a modest $100 yielded 15-20% cash on cash on the hold, today its forcing rents up to top of the market (and historically adjusted highs) and hoping and preying that those rents stay there and continue to grow (not to mention interest rates).

I get the buyers motives and benefits. 

Benefits to invest in his business for some growth capital. new equipment purchase, and consolidation/restructuring of existing debt.I dont have any financial experience in regards to a business, and  just based on his explanation, something doesn't make sense with his income-debt(i dont know what exactly which is why i am here) My question is : " where is a good simple resource i can use to help me make sense of his books?"

Here are a few options:CozyVenmoZelle - Works with large banksPayPalThe benefit to having a lawyer write up your lease is if you have unique situations. 

In addition, your going to need to adjust comps up or down depending on bedrooms. 

So basically I’ll be busy with my current job and unfortunately won’t be able to benefit from a broker’s front office, or training, or support network just yet (hopefully in a few years).  

So in my experience, the lender just manually adjusts for that.  

Here are my comments.1) If you look at your ad, Zillow also offers two other units for rent cheaper than yours if you scroll down on the ad just a bit ($775 and $800) for rents. 2) Pictures look good but there are too few. 

So that is how we got rolling in the early years.I do suggest that method, as we benefit from debt pay down, appreciation, inflation and the renovations that we do.
