Every real estate agent I've ever known has always wanted as much foot traffic through the place as SOON as its listed, maybe even have a few interested parties lined up before it's listed. 

We know going in (for the properties we favor) that it will be "x" per sq foot for flooring, paint, etc

I'd do a rough design of your added spaces to get approximate sq footage of the new construction, then look up your local construction costs per square foot and you'll have a rough estimate of cost. 

I will open a child LLC for each rental property I own. - will the series LLC provide anonymity ? 

I'm hoping to get some advice on how to invest my money and get my foot in the door. 

I'm currently purchasing my first duplex this month to start house hacking to put my foot in the door of real estate.

Interior features include 9-foot ceilings, eat-in kitchens with Energy Star rated Kenmore stainless-steel appliances, spacious pantries, granite or quartz countertops with undermounted sinks and premium Kohler plumbing fixtures, custom cabinets, in-suite full-size washer/dryers.

I didn’t want to make any changes and shoot myself in the foot.

Prior to passing she asked if I would allow him to stay for a short time to get this footing.

I suggest working somewhere in the field and getting your foot in the door and taking it from there.
