I'm not opposed to subject to, but my fear is whoever I am taking over the existing mortgage from will not continue making the payments.You make the payments.

But, it covers enough of the basics.Again, believe what you will.

Hello everyone, I purchased my home two years ago, and currently, I have a tenant renting a room for $800, which helps cover my mortgage.

Computers can analyze property based on subjective data (square footage, # of beds/baths, etc.) but cannot calculate for objective data (quality of kitchen cabinets/counters, size of bedrooms and bathrooms, view out the living room window, etc.).You should study the market yourself.

Profitable months cover non-profitable months, so budget and expect it.

So in reality our MTR rent -- especially in the off season -- pretty much covers the utilities, furnishings deprecation, and another hundred bucks or so, at least in the off-season. 

I am currently house-hacking in a new property where the rental revenue is able to cover the full mortgage and then some.

I would need to learn more about my options though as my experience is limited to podcasts and a few articles on that subject. 

lastly there are plenty of locks you can put on these switches or covers which you should invest in. 

I get an insurance policy for each guest so if they break anything, I feel covered.
