I am thinking of renting a shared office space unit (admin secretaries are there 8-5, 5 days a week I would be there 4hrs per wk... hypothetically) that I would use exclusively for business only to meet wholesale clients and suppliers.

my situation right now is i do all the legwork. my realtor and i find the properties. we walk the properties and come up with a rehab price. the deal is given to the investor, and if he likes it he buys. he then deposits the rehab $ in my account, sometimes in increments if its a larger flip. the property gets sold. i get 10% of profits. only other $ i make on the deal is if i have time and do any of the physical work, then i can pay myself.walking anywhere from 10 to 40 properties a weekarranging and making deals with suppliers and workers to keep costs downtaking responsibility for project getting done for the amount i quoted it to bei wouldn't consider doing it for a nickel less than what i am right now, and often times that isn't enough. 

We have charge accounts at Lowes, Locke a Supply, etc. and every purchase at suppliers we require a PO # which is the house address for the items purchased.  

So at the closing, you might be presented by the title insurer with an affidavit to be signed by you that states that you have paid all contractors and material suppliers in full; this could be problematic ...

If you have never rehabbed a house before, make friends with a very good general contractor who has crews and suppliers and project management skills that you will not have.

You may have issues with material suppliers too.

Find out what types of approvals you will need from the Historical Commission and how long it takes for them to approve.You might want to track down your local architectural salvage suppliers and get an idea of things they have that you might want to use.

looks good, however your kitchen designer/supplier forgot to finish the interior of those glass cabinets..Sorry I'm a kitchen designer.

I look for multiple suppliers of employment, industries, government, the average median income, cost of living to rent per unit, demographics and the momentum in demographics in that market given the culture, jobs, and lifestyle etc.

You're in a pretty good area around Fremont to pick up on some cash flow relatively speaking, and I hear Tesla is attracting more jobs from suppliers..
