Your rents look high to me for one bedroom and shared ‘everything else’… but I’m not into boarding houses, so I may be out of touch there.Maybe some bad assumptions?  

I think another assumption of hassle free, no cost 4% resi investment mortgages is incorrect. 

Assumptions:1.

First, just regarding your assumptions, if you're buying this with a primary residence loan, you can put 10% down (or less, usually 3%-5%).

On the other hand, because I'm buying it at a discount I kind of see that as being able to resell it for free in a pinch, but that assumes the market stays elevated and I don't like making assumptions.

@Michael HaynesI learned a long time ago the hard way to be careful about making assumptions on people and things.

The range of offerings is great, and no assumptions should be made; you need to ask very specific questions regarding who is to do what.All the best to you as you begin your investment journey!

Issue is getting the seller to go for it.. unless there is a formal assumption and the seller is relieved of their liability to the existing mortgage the seller remains on the loan and therefore if its a loan reported to fico it stays there and if its a loan that has a possible deficiency judgement against the owner that stays there.So its no issue really for you as a Buyer the main issue is risk to the seller  IE you default and the seller is in some tight spots.. they have a mortgage in their name but do not own the asset you do. 

Let's do some quick math here...Here are my assumptions:1 million listings - I know the number is higherbookings/year per listing: 20 - I get 60/yearaverage traveler service fee $150 - mine average $400tax rate: 5% - mine is 11.2%How much money is Expedia making by not fixing this bug:1 million listings x 20 bookings x $150 service fee = $3,000,000,000Taxes on that revenue @ 5% = $150,000,000Service fee on those taxes (3%) = $4,500,000/yearMy assumed numbers are VERY conservative....so the overall amount is likely significantly higher.

So, I am going to make a few assumptions:1.
