During dynamic economic periods, interest rate volatility can increase and move mortgage rates quickly. As a mortgage shopper or holder, these periods offer both risks and rewards. For example, you wouldn’t want to lock yourself into an interest rate that drops before the home closing, but you’d welcome a rate lock if rates were on the rise. Some mortgage lenders address this problem by offering rate locks that protect you from rising rates but allow you take advantage of a rate drop before closing.
You can opt for an interest-only mortgage where, as the name suggests, you just pay the interest every month. However, you’ll have to pay off the capital eventually so it’s important to have a repayment plan in place. The number of lenders offering interest-only mortgages has reduced over the last few years because there are concerns that many of those who have them have no repayment plan in place and could be left unable to pay back the capital at the end of the term. 
With a fixed-rate mortgage, the interest rate will not change over the life of the loan. It's a good choice for someone who likes the certainty of knowing the mortgage payment will never go up. ARMs start with a lower interest rate for the first few years and adjust after a predetermined period (usually five years) based on the housing market. This type of loan can seem risky as interest rates have the potential to rise significantly, but there are caps in place to keep the rates from rising to astronomical levels.

Note: If you pay half your house payment every two weeks instead of one monthly payment, you’ll end up saving money on your loan. You’ll wind up paying 26 payments per year, one more payment annually than if you just paid monthly. The re-amortized loan will eventually result in more of the payment paid on principal and less on interest. The extra payments go to pay down the principal on the loan.
Mortgage forbearance programs are offered by numerous lenders, including Bank of America, JP Morgan, Citibank, and Wells Fargo. Forbearance allows borrowers a temporary suspension of their monthly mortgage payments. So a homeowner will have time to explore their options, receive counseling, or modify their loan during this timeframe. In addition, a foreclosure on your home will not occur during the forbearance period. Learn more on mortgage forbearance.
