Let tenants know you will continue to advertise the unit until it is paid for.

I don't have the 20% down payment plus closing costs available in cash right now but would like to continue to buy properties.

For purposes of having a commercial space, for business credit, applications/requirements from many companies and to keep our incorporation in the state of Oregon, we are currently leaning toward continuing to rent the cheapest office unit month-to-month as our Principal Place of Business just to meet the requirements of state incorporation/other companies.I'm certain that we are not the only virtual business to face this dilemma... has anyone found a solution to this.. perhaps a method or another state that permits virtual businesses without a physical presence to be incorporated in their state?

You'll want a clause in th contract that you'll agree to wait a max 3 months then have the option to decide to continue to wait or extend the waiting period.

I could continue working with different applications, but one hub may be easier. 

Continue to invest and if and when the market falls then you will be in a good position and have some great opportunities to score discounted real estate at bargain prices from people who didn’t prepare .

However, my realtor continues to focus on the prices of homes whose rehabs are not even comparable to mine.

I have been using the money I made those first 2 years to start other businesses and now to continue to flip and rent.Because of real estate, I get to be at home and watch my two young kids grow up without having to be sent off to day care and get to travel with my wife and family.

Would you just suggest showing up at his place of business if this continues?

May be a better play for developers/syndicators who can offer some tax protection to individuals looking for long-term investments.
