Nothing wrong with that, but you need to set realistic expectations that if you are taking on a huge debt load, the payments going to be higher. 

(gross rent minus expenses, lighting, debt service)Currently, the deal is priced at about a 9% cap rate, so I imagine the location is quite rural?

If not, then it seems that every time I buy a property I am acquiring the debt without the benefit of using the income to continue purchasing.

The electrical has some exposed wiring in the attic crawl space that needs to be in a junction box and to restore power to the detached carriage house where my cousin lives.As well as a handy man to grease some reluctant windows and fix a leaking valve as well as smaller issues.Looking to get multiple quotes if possible.Can anyone recommend any good people who might be able to get to this soon?

Both my wife and work and we own several properties with super-pos cashflow, mixed in with little mortgage debt and helocs. 

My debt to income is too high without it even though I've been renting the house out for almost a year with a solid lease.

be using agency debt..... 

I'm pretty debt averse, so taking a loan out period is a big step for me.

Cash flow would be slightly more with 4 single families, but we're not looking to get rich quick here and the cash flow on the commercial building would suffice, plus appreciation, paying off debt, and doing small rehab to the vacant property along with renting it out would increase value with additional rent.I run a business with 40 employees and understand the business side of things pretty well.

The government had a lot of debt from the war and artificially kept interest rates low and let inflation take care of the debt.
