Current occupancy is I-1 (institutional). there is an auxillary building that is connected to the primary building with 2-hr fire separation that I am planning to convert into 24 one bedroom/ studio apartments.

Never built a home that a buyer didn't bring one in.  

The rules can vary from building to building, so you’ll want to make sure you’re clear on the HOA restrictions for each one you’re considering.

I am not saying every sales agent is influsnced by this, the best ones understand the importance of brokerage relationships and will not want to hurt their reputation within the community by having  word spread that they are being unresponsive and then the MLS shows the dual agent settlement but there are instances when this happens. 

And you also get to use part of the property for your primary residence.Here's the end game - After a year or two you move out, back fill a renter and buy another one.

I don't know whether you are dealing with a 4-inch or 6-inch pipe, but even a 4-inch pipe should be perfectly capable of handling 2 single family homes if it is in working condition.Hard to believe someone installed the clean-out backwards, but unless this is actually where your backup problem originates, I doubt anyone will make you correct that one.

It scrapes FSBO listings from multiple public sources (Zillow, Craigslist, and a few others) and compiles them into one easy-to-filter feed.

In a perfect world, I will retire in Tampa one day. 

While many of the requirements are "good" in theory, like backflow prevention devices on hose bibs, to me it is unfair if they don't require this on every house vs just rentals.While some people think it adds a level of safety or "upgrade" to the community, to me it is a cost and that cost will be passed on to the tenants, who could by choice decide to live in a house without the checklist vs living in one that requires the checklist.To me it is a violation of the 4th Amendment....illegal search and seizure. 

Pricing your unit above market won't cause your unit to take 3 months to rent vs one month to rent at market rate.
