I always like to include some for rent loss too.  

If you really want to sell it and can afford a small loss cut your losses.

As with all lots of residential character there will be a requirement for front, side and rear setbacks resulting in a loss of buildable area further reducing the building size (no permanent structure may be constructed in setbacks)  Depending on city zoning ordinances there may a provision of a zero lot line (meaning possible reduction of side yard setbacks)  with zero lot lines it may be possible to build a  20 foot wide structure, however you may be restricted in height and required to provide additional fire protection between your property and the next.

Speaking from my single property experience, I found that by marginally increasing my rent kept my tenant for another year at increased rent versus trying to go to the top of the market and potentially taking a net loss by having to re-tenant the property.  

Would you cut your losses and start looking elsewhere? 

A friend of mine that has a 130 unit gets about 75% to pay, 10% more after collection, and the other 15% he eats rather than evict and spend thousands per units and lost rent to get ready again.If those types of systems are present he just builds it into his offering number and counts on certain non-collectible losses. 

This could be a bad move, as if a loss occurs your claim would likely be denied since it's vacant, with no effort/intent to rent.

Just know that setting yourself up to be succesful isn't a loss.

Start talking to everyone you know, asking if they know anyone who's tired of the stock market losses (ask them how much THEY lost in the '08-'09 crash- average is 40%- rub it in,)  have a self directed IRA or other available funds that they'd like to invest in a secure, tried and true investment medium.

In this kind of relationship, I typically advise my Texas clients to be 50/50 on ownership and profit and loss BUT the manager takes a reasonable management fee of the gross or net revenue, but, I also advise to pay a small amount of interest on capital accounts so the money man gets some compensation for fronting the money.
