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. 

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 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.  

The added benefit of this process is that you can also have your attorney sign the public records as "Nominee Trustee" before assigning yourself as the "Trustee" once the trust has been established.

The point of all of this is for him to benefit from it, make passive income and i get to know he isnt working anymore.

As such, you need to be confident in your comfort level with each inspection, and at what repair level you'd take it as-is (basically), where you'd take it but based on a lower negotiated price to repair/renovate items, and where the cost is to great to proceed.When I walked from my first cost/benefit analysis, it stung a little. 

One of the great benefits of DIYing for us, it turned out this year. 

look at utilities and other added benefits you could upsell to your tenants, but it looks like you have a great deal, just screen properly and be professional firm and courteous to your tenants.

You'd also benefit from the best financing terms when buying primary residence vs strictly an investment property.
