You have to find the right balance between making attractive offers to buy deals and protecting your investment.When I purchased my first 4-plex, I saw 3 out of 4 units prior to making an offer.

It's better to have a property vacant or charge less than market to attract a high quality tenant then to get someone in fast. 

Surprised you can't build attached with RSA-3 Zoning. 9' would definitely not be wide enough to attract tenants or buyers.

With quality photos, your property advertisement is able to stand out and attract the attention of potential tenants.

This is obviously a subtle advertising post to attract investors, without getting flagged. 

The rates are still low enough to make the rate almost as attractive as the investment itself (that was borrowed from @J Scott).  

The home is in Wisconsin, and is a three unit producing 1900 a month in rental income.

I live in the Pacific Northwest, I'm a bit priced out of the market, I'm attracted to buying a duplex or fourplex in some state in the Southwest or Southeast where I can better afford to buy, I would like to move there and live in one of the units, but it seems like an overwhelming project to decide where to buy it seems there are a lot of factors involved and it's difficult for me to come to a decision.

But at face value, the three currently rented units produce $2095/month in net income, so it seems like the cash flow could be great, but then when I plug everything into the calculator tool on BP with 8% vacancy, 10% property management, 10% cap ex, etc, I actually end up with a negative cash flow. 

@Dwight Cook if the property is producing income it may actually be easier.
