However, bad tenants can be everyone’s nightmare- they might pay their rent late, cause havoc with the neighbours, treat an owner’s property like a tip or unreasonably demand endless costly repairs.

This is my full time job now, so best if I treat it as such. 

You want an accountant that can help you strategize and who is responsive when you want to know the tax consequences of the decisions you are making throughout the year.House hacking will complicate your tax return.Your property can be treated as both an investment property and a personal residence.

The hardest thing is to actually pull the trigger and buy your first property because you want to make sure it is a good deal and you don't lose money but if you do happen to lose money then just treat the loss as you paying tuition to gain education.  

We have a No Smoking clause in all our leases, if that is your case then keep as much as you need to treat the carpet, but I think using their deposit to replace the carpet is not being fair to the tenant.. 

It is easier to know the situation before you close, not after.Personally, I haven't had a lot of issues with tenants - I try to screen well and treat others how I would like to be treated. 

Many people treat their pet(s) better than others treat their kids, and those tenants have a harder time finding rentals so often stay longer.

A contract can be treated rather much like a commodity, if you hold/own the contract you control the property. 

Nonetheless, I am still treating this very seriously as if it was not family.

If you can't get one or two closed within the time then treat them as separate exchanges and use the 3 you could bunch to purchase a larger building.
