Just check the local rules to make sure you’re good to go!

Stairs are the only way to get in, no grab rails in the bathroom, ramps that are too steep, etc.From what I've read, all commercial businesses/buildings (including ones before the ADA was passed) have to comply with the rules, unless it would be outrageously tough to fix (like installing an elevator in an already built building).Are all these local business just not complying and taking the risk, or am I missing something? 

Each town has different rules regarding rent control. 

@Joy Daniels I have one of my STRs in that market on Anna Maria and each “city” on that 7 mile island has different STR rules.

A self-directed IRA could be a good way to defer taxes, but there are some rules to keep in mind—like keeping all the income in the IRA until retirement.

A good rule of thumb is to have 3-6 months of expenses (mortgage, utilities, insurance, etc.) set aside per property for emergencies.

@Polat CaglayanI've never seen a formula but here is a general rule of thumb for multifamily:The class of an apartment refers to the quality of the building, which can be determined by a number of factors, including age, location, and condition: Class A: These are the highest quality apartments, typically built within the last 15 years.

Quote from @James Hampton: That's a bad practice to follow.If an occupant is not named on the lease, you may have difficulty enforcing rules or evicting them.

So if I understand this correctly, by qualifying to extend the 5 year rule to 10 yrs, $250k if single or $500k if married of proceeds from this sale would be exempt from capital gains? 

Sad that NY isn't taking advantage of expensive hotels to get most of the US traffick to stay on US side and just do a day visit to Canada side and come back.I don't know why small towns change their STR rules and make restrictions.
