If you are debt free and making $10,000 a month, that means you're making double what the average family makes in this country.Personally, I think you should take some of the equity from your existing homes and leverage that to buy a few more investments.

@Anthony Paul Guglielmi  Are they on an existing lease? 

I think there's more to consider than just money, to include your existing tenants' right to quiet enjoyment.

I would like to understand what general tax benefits exist if 100% of rental profits are reinvested into new properties.I own, through a LLC, a few rentals which are fully paid for, and am in the position to just reinvest all profits.

How do I co-exist with my mentor in the same area without souring the relationship?

They are issued and signed at the same time as the original lease and are additive while an amendment is signed at a later time and revises what is existing.

My question regards how the lender is calculating income in the debt-to-income ratio based on the existence of the partnership.)If we treat the partnership as a standard business, our DTI is unfavorable:Net rental income: $7600Other income:        $3000Total:                   $10600Debt:                    $ 6000DTI: 57%A DTI of 57% is above their limit.However, since Net Rental Income excludes $1000 monthly depreciation (non-cash expense) and $2,400 interest expense (part of the proposed debt), we were initially told that they would add back depreciation and interest expense, leading to a monthly income of $14,000, and a debt-to-income ratio of 43%, and that DTI would pass muster.The loan went to underwriting on that basis, but underwriting decided that they couldn't add back depreciation and interest expense, since it's a K-1.

Do you perform an annual walk through of your unit each time an existing tenant renews a lease?

In this case, The owner has an existing mortgage, So my attorney will be structuring a "subject to" type of finance deal.

@Dale NuzumWhether the strategy makes sense or not will depend on a lot of details.As a means to utilize existing tax-deferred retirement savings to capitalize a business expansion, a ROBS would absolutely be the correct tool for the purpose.
