You're wrong to calculate this as a 7% return, I think. I live in Blaine. Is this in Club West? I see 2BR's listed for $159.9k. No matter the location, all homes sell for less than list. Let's say you sell for 92.5% of list. This is $147.9k, subtracting 6% for realtor fees and closing leaves $139k. You would only be able to walk away with $9k, and walking away also "costs" you $8k in lost equity that you had to pay the Realtors. It sounds like your original loan was for around $160k-$165k if you can remove MIP in November.
Since you would only take $9k with you, we can count $9k as your cash investment if you keep the home instead of selling it. You said the $950/month includes principal, interest, taxes, insurance, and then another $220/mo for HOA for a total of $1170/mo. The HOA takes care of lawn, snow, exterior, I assume, so that's $0. Your tenant should take care of all utilities, so that's $0.
If you rent it for $1550/mo with a month of vacancy per year, you will receive $17,050 in rents per year. Subtracting $14,040 for principal/interest/taxes/insurance/HOA, that leaves only $3,010. Are you responsible for any mechanical that would need replacing -- anything with a service life besides appliances? If not, repairs should be low each year, but budget maybe $1,000 anyway. This leaves only $2,010 of cash flow per year. Not a lot, but that's a $2,000 return on a $9,000 investment, or 22% cash-on-cash returns. You'd also be keeping some equity, maybe $2k/year -- something to consider.
Another benefit of keeping this property is that you know the home and area. If you don't like being a landlord or it doesn't work out, you were going to sell it anyway. If you rent it for 2-3 years and decide it isn't for you, you've earned enough equity (which the tenant paid for you) to cover realtor fees, and you can exit with more cash.
