If you run out, you’re dead in this business.

My advice is focus now on building your branding, business and client base in real estate.

Depending on the location of your properties, an assistant might be much better than a property management company.

It also depends on how you hold your properties; LLC, S Corp etc... as to what the agent will recommend.

Here in Chicago, you should expect a range from $200-$275/SF, depending on the location, experience, labor, and material finish level.Are you in a position where you already own some land, or what is your current situation?

as far as cost that depends on too many factors to cover! 

The stabilized properties operate fine without me but the development side of the business requires me 24/7.

But it just depends on your risk threshold and how much you're looking to spend.  

.: Quote from @Michael Plaks: Quote from @Ashish Acharya: @Anirudh ReddyWhen it comes to a seller-financed property, who claims the mortgage interest depends on who’s responsible for the loan and who’s making the payments.

I do not sell my model but I have a friend in the business who offers a much better model than Michael Blanks in my opinion.
