Thank you for the links and information, interesting. I would expect the rate to be higher to be honest, less than 3% even these days is low, my 5% example is from offerings I have seen for interest only.
It won't be let all year round being a student let I imagine, what proportion of the year is it let? Are all the rooms always taken?
140k sounds cheap to me for a 3 bed 2 reception room house, I would expect it to be small and not in a particularly nice neighbourhood. I would also expect your maintenance and management costs to be fairly high compared to other buy to lets due to students.
So bearing all those things in mind I would not expect a clear 800 a month profit all year, I would expect the average to be less. However I can see that you could be making money here for as long as rates stay low.
However I can also see those gains being lost as the value of the property devalues, it wouldn't take more than a 5% drop in a year for example to relieve you of an unlikely 8k a year profit.
So from a purely financial perspective it's a tad on the iffy side in my view, but actually potentially beneficial. However bearing in mind where things look to be headed and when you bought, and how,you're relying on such low rates to get anything, there are better options out there.
However what would stop me in my tracks is the thought of stuffing 4 students into a small house in a rough neighbourhood and releiving them off what to them would be a substantial amount of money. We all roughed it as students, but I feel this is on the exploitative side, and so not to my taste personally. In my student days I'd visit friends in house shares like this and they felt ripped off, landlords were always despised, accommodation was always poor with cheap and nasty fixtures and furnishings etc etc.
Good luck to you, and again thank you for sharing so much. But not for me, and I'm afraid I don't have much respect for those that do get involved in this part of the market.
I expect you to see some positive cash flow in the short term, not to the extent you have made out, but positive none the less. The medium and longer term however do not look good in my view.
