There are a select number of homes in the 2 million dollar range and up that do produce positive cash flow, but those are newer oceanfront  homes with tons of amenities and upgrades and the maintenance and upkeep is brutal to keep up with the demands of that higher end rental customer. 

Ya its an easy extra bedroom but typically I would think a garage would out weight a bedroom.

The odd weight tends to get it opened first. 

You can def make it work but you'll have a lot of turnover, wear and tear and upkeep on the properties. 

You will need to make adjustments to the entire floor occasionally, especially in the beginning when there isn't a lot of weight/friction. 

Charter schools like Drew Charter (highly ranked statewide) in Kirkwood is a good example of how you can have a poorly rated school district but a great Charter school that anchors the area.OTP, you have to put a lot more weight on school ratings.

No restrictions on breeds or weight since it can't be effectively policed and is just stupid in my opinion.

In most college towns it is easy to stand out if you upkeep your properties.

@Charlie Moore hopefully you have some clause within your lease that spells out that the tenant's responsibility of upkeeping and maintaining the property (including lawn care)

There’s no problem anticipating that rentals will provide for your family there’s 3 things to consider:1) legally set up operations so that your beneficiaries can simply continue them without any kind of weight of going through probate (other wise a little life insurance for probate season can be helpful- this should really be a conversation with your lawyer if you have questions about probate - thankfully @Pat L.’s doing the right thing with the trust).
