Just keep in mind zoning and code requirements. zoning is usually not a problem, but when a commercial is converted to residential current codes must be met which usually means two stair towers, fire separations, and sprinklers.PS: Loopnet is what I used to find my warehouse.

Home Depot & Lowes are fine for commodity items.

I've taken the lifespan and current age of the item (many do not add current age but I don't understand how you can be accurate without it) into account to estimate the remaining years until replacement is needed.

I'm currently a RE agent up in Cherokee county, maybe we could get together and brainstorm... 

In the current market with the prices of homes being so high does it still make sense to be investing in real estate or to be accumulating cash and waiting to see where the market goes? 

I was unaware of this particular situation until a current client of mine alerted me to this post.

Average housing price in Detroit is still really low compared to the national average and Detroit's appreciation over the last few years has been good and trending well. 

I currently have 5 units that I purchased with my own money, and I am now turning to friends, family, and colleagues to raise capital for future purchases. 

However, when I purchase the home it was being used as a single family, therefore, the loan I currently have is for a single family.- When I bought the house, I renovated the apartment and it is currently being rented out.- My question is do I do a cash out refinance or take out a HELCO (the mortgage broker I used originally advised that)?

You can buy another primary once you vacate your current primary and converting into a rental property.
