How much would you pay for small business (appliances store) ?

I been learning appliances repair for past few months. I can fix all kind washers, dryers, gas/electric stove and ovens. Getting my hands straight on friges now. My boss is going to retire. He is willing to sell his business to me. He buy applianes, refurbish them and sell. He gets enough calls to repair for local people. Here is the business data...Profit from sales between $5000- $7000 Profit from delivering them $1000 + Call Repairs depend on him but he easily makes $500+ Parts sales profit $500 +So basically his profit is abover $7000/month. Rent is $1800/month. 2 years of lease agreement left.He works 9-5pm and he is not putting his 100% cause of his age/retiring mindset. Profit could be raise up a little bit more if with good customer service. He doesnt do any advertisements or anything. He been on this location for over 6 Years.He has $5000-$7000 inventory. This small business needs labor. I dont mind running this business. How much should i offer him? It's my first time buying a business. via /r/business http://ift.tt/2Ag0Nan
