I've seen more and more apartments being built even around Henderson which was almost exclusively SFH.  

Options include driving for dollars, absentee, probate, using listsource if you are not in a competitive market, buying lists that are exclusive for your market type (we partnered with a guy that does this) 3) Start a sustained direct mail campaign.

We are exclusively engaged in SFR markets with most of our volume funneling through from our parent builder.

At the sale of the old property you will start a 1031 exchange but will take boot equal to the amount of your primary residence exclusion. 

If you are interested please connect with me with an explanation of the nature of your business, the cities you are active in, and whether you work exclusively with investors.

Just inform the agent that you work with multiple agents to find deals for you, and that if this agent proves themselves to you, then you can choose to work with them exclusively.  

Regarding your second question, if we are looking exclusively at the effect on your credit scores, then the commercial loan will apply to the credit score of your business. 

Are there any other marketing costs like newspaper, web sites, etc?
