Deltona SFR please help analyze

[Lourdes Del Rosario]

Hi BP'ers! I am just starting and looking for a stable way to retire and take care of my disabled husband in 5-10 yrs. So early this month I've made an offer at full price on this property and doing my due diligence. It is a safe area, cash flowing (according to my calculations $300+/mo) and will appreciate. Can you spare a few minutes of your time and help me?

Is the cash purchase price too much?

Purchase Price $75,000 cash , currently rented at $850 (2BD/1B, recently rehabbed)

Property Taxes $130
Insurance $55
HOA 0
Management Fee $68

Appreciate any feedback I can get...
