So it has its downside.

@Andy Nguyen the only downside is that you have to be very selective on which apartments, some landlords try to charge you more a month because you are doing airbnb and then you can't justify the margins after furniture, insurance, etc etc.

There are some great upsides, and then again their are some downsides.

However, I don't see a downside of putting one down, since it will only be a fraction of the cost of the whole project. 

The downsides typically are that you're maxed on contributions and loans before it becomes a MEC and loses its tax advantages. if you're even remotely interested in something like this, speak with a qualified Financial Planner. 

The down side is mostly time constraint, and any unforeseen snags along the way could cost a lot more time and money.

The only downside to chase is the FEES!

The downside to not doing these small increases is that when the market hit an all-time, high or unusual high like it is around now the tenants have a hard time understanding why you’re increasing so much.

The downside, Orlando heavily relies on the parks for secondary and tertiary revenue. 

The only downside is that it shoots a couple holes in the "people are generally good" theory....
