It was much more stressful and not worth it IMO. 

I don't know your specific market all that well but have you done some analysis on your ADR during the high season X your high season occupancy rate and determined whether taking lower priced slow season bookings vs letting your property stay vacant during the winter averages out in your favor?

Is there a report that says lower priced homes are more likely to have a seller assistance?

.- get into real estate with a lower rate and lesser percentage down payment.

However, as @Chad Hale mentioned, only if you can afford it - meaning both financially and mentally (e.g. how stable are both of your jobs, how long will it take you or your husband to find a replacement job, how much you have in reserves, and whether you guys are in a position to withstand that mental stress, etc.)When you mention 8k monthly, I am assuming that's net profit?

So working with your buyer to negotiate as much value as possible to the real estate and least possible to the business will help to lower your taxes further.

I’ve had several investor clients go with a new (to me)/ unproven lender because of a slightly lower rate promise only to get burned by that lender (closing costs were higher, appraisal costs much higher and appraisal was a nightmare, main point of contact gave us the clear to close as we passed our financing contingency then just before closing someone from the underwriting department we previously didn’t know existed said we need a few more days and seller didn’t agree because they had a higher backup offer, jeopardizing the earnest money and losing the property, etc).

Are costs really lower with a container? 

If you sold it, what would you do with the money and how does the return compare to what you get now (factoring in the amount of work/stress with each option)?

You can get away with using 5% for Class A tenants, but we use 10% for Class B and lower. 3) Tenant Payment Performance: you didn't mention this, but it is important!
