What are the factors that should be considered?

The #1 factor in making money in class d/f areas is market knowledge and knowledge of how to deal with the issues that arise from investing in a high risk area.I grew up in a class d/f area, and Ive invested in those areas in the past.

my name is jeremy. i currently live in guam. i am 24 years old i have 2 amazing children and my beautiful wife. i am currently in the education phase of our realtor investing. i am so interested in investing i have been finding ways to invest money to help me and my family to making through this crazy world and not worry about how we are gonna pay for our bills or work with no reward until we are buried 6ft below. 

I have an opportunity to get a SFR for 45k that is in a rough area but newly renovated with new hvac, water heater, and roof. rent should be 750 per month, taxes 650, ins 900. assuming 35% for capex and repairs and 10% for PM. assuming 8% vacancy factor and 5% leasing.

The hands on approach will help you and ease the fear factor in stepping in and doing your first deal.  

Zoned business and residential.Your choice to make this your beautiful new two bedroom home, office, or combination. 6 Meetinghouse a great place to call home.

Dear BP,I am interested in buying in PR due to many microeconomic factors that make it feel like a good time to buy.

You are correct, I didn't factor in vacancy rate, repair costs etc so that will bring the expense % up.

All depends on multiple factors.
