I'm a peaceful person overall and have always treated my home like my sanctuary up until things have progressively gotten to this point.At this point, I do still want them to move, but I also don't want to tolerate what's become so increasingly common, so I will continue to press on with what needs to be done. 

For example, If I'm putting $5k into 1 unit, I plan on increasing the rents by $140 to return the capital I put into the unit.

After the vacancy is filled, that would add another $1,000 / month.The property is generally in good condition with some upside for appreciation and there are some changes I was thinking about to increase the value, I.e. converting from oil to electric and have the tenants in the residential property pay their own utilities.

She was on a month-to-month lease and so the reason for serving notice was not needed, however, when confronted I told her I was looking to renovate and increase rents.This morning at 4 AM there is a leak coming from the ceiling in the apartment below hers (coincidence?

Some of the renters have been in since it was built without a rent increase.

It can be argued that making that unit legal will increase the value of the property.

You have to figure out instead what you can be doing that you are passionate about to increase your money 200k,300k,500k a year etc.I want to live for today.

He said that they purchased an asset with rents that have not increased in 5 years (can't remember exact amount).

I was able to work with them to get a 5% rent increase put in place within 2 months of closing.

My question is if it's always better to purchase properties in cheaper market where it takes less capital and the rent to price percentage is easier to get above 1% or if it's worth investing in a city like Denver where it's very hard to get the rent/price ratio over 1% but the cost of the real estate increases much quicker than it does in other less desirable places to live?
