I have particular strong feelings about this, but I may be the exception.The insurance and annuities side of your business will be a very distant next area of importance for me, but for a younger person that needs to provide for a young family without other assets this might be a little higher on the list for them.There is a financial planner in my local market that will also shop insurance providers (including car, home, health and rentals) to find the best value on insurance as part of their service for their clients.

I am still a bit of a newbie investor but do feel like I can add value to a project through being a licensed realtor, current business ownership experience (5 years owning an insurance brokerage), and having some capital to invest.

I see so many room illegal additions/conversions where the homeowner spends a lot of money on the project, but when they sell the appraiser assigns it no value because the square footage is unpermitted.

This is area specific, but for me it is attorney fees, transfer tax, tax adjustments (county, school and village) title fee and title insurance on the buy side.On the close side it is attorney, transfer tax, tax adjustments, and realtor fees.My latest house ($120k purchase) cost about $8500 to buy and will cost around $11-12k to sell.

Taxes/Insurance are $252/mo. 

My wife recently purchased an 8000 watt electrical ceramic kiln, 240V 1 phase power, 33.6 amps.I am installing in the basement of my home (owner occupant, not in a municipality that requires an electrician's license):1. 50 amp dedicated breaker in the panel, per kiln manufacturer's recommendation.

A contractor is a licensed and insured business , they provide you with a written estimate and scope of work .  

Is there resource the owners or I could use for repairs like insurance?

In FL many absentees are second home owners as people get ready to move down for retirement.

It's not like talking to Suzy Q homeowner with a 90k house.
