You may want to wait a few years before considering it, last time I read an article about it they were mentioning new technologies and manufacturing methods that will greatly reduce the cost of the panels.

Sure a 60 amp panel is small by today's standards but do you really need to spend $25K to address it?

It has a lot of panel discussion where you can ask questions and also has small group break out sessions where you can get very targeted answers to questions about specific aspects of real estate. 

You need to give some more context so we can answer your question better.In my sub market, with the fix & flip deals I'm doing, the best value add for appreciation is putting in new flooring, baseboards, paint, cabinets, countertops, appliances, light fixtures, ceiling fans, plumbing fixtures, toilets, bath tubs, landscaping, windows, doors, electric panel, sewer, roof, and HVAC.

They replaced the breaker, the control panel, the circulator pump, a zone valve, bled the furnace and water heater.

Advice please....I bought a duplex that needed a new flat roof (it was fine but was 18 years old), electrical panel changeout, and hurricane protection.

Added solar panels and L2 charger!

If you need to add plumbing or work done to your panel, get a professional.  

Any electrician should be able to able to connect a generator to your panel and check the electricity.

After some negotiating, we got it under contract at $240k, and celebrated on the contract signing date, because I knew we just made money....We negotiated another $2500 off the contract price to help replace the electric panel and closed at 237,500 with 3.5% down, FHA...In the next year we put about $30k into the house including the following improvements10mm laminate flooring throughoutcomplete remodel of master bathpartial remodel of guest bathnew panelnew ACnew paint inside and outminor roof repaircouple new windowssome new appliancesnew drivewaynew front landscapingI know it's important to have an exact figure...in that 30k I'm rolling some furnishings and fixtures into it..I forgot to mention we also have a large yard, and no immediate neighbors behind us..great lot in this neighborhood.
