[Calc Review] Help me analyze this deal

[Elliot Friedman]

I am looking at a property that currently has three bedrooms, two bathrooms and an unfinished basement. If i finish up the basement i can make it two bedrooms and two bathrooms and rent each bedroom out individually. Based on the local market, i believe that i can rent the rooms for $600 a piece. 

5rooms*$600 = $3,000/month

Expenses

		Expenses			Debt service			Income
	HOA	225		Mortgage	891		1 room	600

	Utilities	300		Taxes	134		master bed	600

	Total monthly cost	2290
		Down payment	15000				Basement bedrooms	600
5bd 3b		Basement fix up costs	35000					600
		Totaling invested	50000
							Total income	3000
	COC	0.1704
	Monthly cash flow	710

Please let me know if this makes any sense. If i were to rent out the house on its own, I would maybe get fifteen hundred dollars a month.

I am a new real estate investor and it was my realtors idea to finish the basement off. The deal only makes sense if i can finish off the basement for a very reasonable price and i can get the rents i think i can get.
