A: Depends on what the contractor is doing, and if he is truly a contractor or a handyman. In Florida, Handymen typically work on small jobs, like minor repairs and improvements to a residence or commercial building. In Florida, you don't need any authorization or documentation to provide unregulated handyman services, but you will need a contractor's license for regulated services like plumbing, construction, and electrical work. Contractors obtain building permits for their work and to make sure they comply with zoning and building codes. If remodeling your kitchen calls for plumbing or could be considered major construction work, then you need permits and a true contractor. If he is a real contractor, and he is doing this work, the city can assess fines on you and stop the work until the permits are obtained.
A: It depends on your policy. Interest rates for personal loans are either fixed or variable. The fixed rate remains constant throughout the loan. However, variable rates may be increased or decreased, based on market changes.
