For example if they felt the owner ignored their maintenance requests, you may be able to start off on a better foot with them by assuring them you will take their requests seriously.I'd also consider that you may not want a vacant unit in the middle of winter, so if it were me, I'd probably spend the first few weeks getting a sense for these tenants, their issues, etc. and determine if you think they're going to bad-mouth the property/you to others.I guess as long as they seem like relatively reasonable people (i.e. not hostile), if you still want them to move I'd probably defer to giving them 90 days notice and basically tell them you're giving them more notice than you need to because you want to make sure they have enough time to move.But also tell them based on how much you paid for the property you absolutely need to raise the rent - it's not a question of your being a nice/mean guy, it's a question of making the #s work so you can afford the mortgage payment.I'd also consider searching out some community organizations and contact info for the Department of Elderly Affairs and anyone else who might assist older people in finding new living arrangements, and include that as a second page to the rent increase notice.A lot of questions like this depend on the specifics of the people involved, whether you can build a rapport, understand and possibly address their concerns, whether you think they're acting in good faith, etc.So it's hard to really give an exact answer but those are some thoughts.

Dear Saran,Thanks for your comment.

Start by contacting your local building or planning department to figure out if you can re-zone.

My passion for Real Estate was inspired by #1 my husband and 2 other very dear people, Roy Cleeves who 15 years struggling to make mortgage payments, decided to purchase an investment property, and before long Roy purchased another, with now owning 18 properties and growing.  

In addition the building department thinks it's a major metro area so within the City permits are a HUGE hassle according to the contractors I spoke with.

If the SPD is not available, the plan administrator or human resources department should be contacted for a copy of the most updated version.

As others have alluded to, the property will be left in better condition at move out when the departing tenants know that they will then receive a large refund.

I actually reached out to Fort Collins' zoning department about this a week ago.

The rental department of your brokerage knows who owns a lot of property in the area as well as some agents who have been around for a long time. 

I'm going to start with my zoning and building department and take it from there.
