Don't get me started...America is headed there.

I replaced a furnace at a rental with in base model, I don't recall the BTU or efficiency off the top of my head, but it was $3450 so I would guess you are going to be upwards of $6500-8K depending on sizes. 

This was the first successful commercial conversion project to be turned into workforce housing right here on Hilton Head.

You are heading in the right direction to get the financing options laid out and then find the deal so you can pull the trigger for the right one.As far as HML options be sure you get all the details before signing anything . . interest rate, payment terms, what if you need to extend, points up front, etc

If you want to check out market data, head to websites like Realtor.com, Zillow, and Redfin, and partner up with seasoned agents who focus on multi-family properties.

Heads up - HELOC = Home Equity Line of Credit.Makes sense! 

You kill two birds with one stone by giving yourself a roof over your head and an investment property at the same time. 

I know that, overwhelmingly, it's what you fill your head with that counts, it's the day-to-day actions you take, it's the spouse you marry, it's the systematic choices you make, and perhaps most importantly, the personal hypocrisy you don't allow yourself to get away with.

I recommend googling "(City name) comprehensive plan" every city has a city plan that shows where their major commercial projects are heading. 

That is the direction I am headed as well.
