The third floor has 2 bedrooms and an extra room (same size as both of the bedrooms) being used as a living room.

Are there costs associated with pulling out equity on your home, extra payments? 

The extra money is worth it for an agent that'll service you and get the job done well. 

That's a total loss of $4,000 in an effort to lock a tenant in for an extra 12 months and reduce turnover costs!

First, learn how to run a park that already exists, maybe one with some extra development opportunity.

I asked and they told me that the person assigned to the claim said to do this as they were basically guaranteed to get approved for that extra money.

We ended up closing, but it cost me over $1000 extra to have the attorney get involved to let the world know that we were prepared for a fight. 

It may sound nice to pay a 6% management fee but the extra fees can add up to be more than the other company that charges 10% with no additional fees.

If you want to do a short term rental you are starting an active business and if done correctly you will make much more money but depending on your skill and the systems you create and master the work to extra income may be less than a different job or business and you need to look at work seasonality and risk not just one aspect.

If anything, charge extra for anyone paying by check or money order in the office to compensate for the additional work it takes to manually deposit those funds.
