Don't allow 3 adults but not a combination of adults and kids; treat all bodies the same and apply it consistently.

If you think the cleanup costs will be higher as a result, such as to remove smells/stains, you could tell them.I had tenants a few years back that were incredibly dirty.

However, maintaining a cushion for those times when all hell breaks loose (the boiler needs to be replaced unexpectedly and tenants forget that paying rent is a priority) will also make your life better and allow you to make better choices (as in do not rent to any warm body...an empty apartment is much cheaper than an occupied apartment with the wrong tenant in it).Good luck

I read body language and although they are very charismatic.... they failed my test!

It smelled bad the whole time. 

This is my first experience as a landlord, and what a headache this one tenant has been.When the lease with a pair of tenants renting our condo lapsed, they never informed me that they desired an initial inspection, despite my offering of it to them in writing with about 45 days left on the lease.After they vacated, I had a brief list of things that needed to be addressed:The condo was much dirtier than when I initially handed it over to them (I hired a cleaning service to do a 'move-in' cleaning of the empty unit before they moved in).There was a nickel-sized hole punched through one of my floorboards with some kind of cheap resin patch job done to address it, this looked like someone jumped on a couch and put the foot through the boardThe carpets in both bedrooms where pretty dirty; not vacuumed and had an off smell to them.

It is advisable to do your due diligence and ask about such things as how long have they been in business, are alternative assets their sole focus, are they BBB accredited and rated, are they a regulated financial institution, have they ever been sanctioned by any regulatory bodies, how many accounts and how much in assets do they administer?

No body can eventually force you to buy something you dont want.

They explain how they have been having water issues in the basement and no body wants to fix it.

At minimum it will become an added storage area for him and worst case the garage will turn into a body shop where he is repairing his bike and his buddies bikes.If he didn't rent the apartment under the pre-tense of being able to use the garage I wouldn't let him.
