Mortgage to rent rules


Frequent Poster
Two of the rules for eligibility for MTR are:
1 Income (net?) of not more than 35000 p/a
2 Assets of not more in value of 20000.

If a person who has been in MTR for a period, now eg thru promotion or change of employment becomes in receipt of a higher income, say 45000, must they now leave
the scheme?
Or, if they become possessed of cash or assets greater than 20000 (eg inheritance) would this also mean they can no longer stay in MTR?
