It Seems to be flooded lately with people who try to get connected with anyone and everyone willing to accept them so they can inundate your inbox with advertisements. 

I am thinking of either going through an online funding platform or advertising the opportunity or using crowdfunding.Which would you advise me to start with.Note that I am excluding taking a loan here because I am only 18 and in university, all banks said they wouldn't lend to me.Thanks!

You can spot these deceiving types by their advertising, "learn the secrets to" stands out and is probably the most abused, as real estate transactions, methods and strategies go back in history.

your 7% maintenence/repairs and 8% vacancy numbers are made up numbers..they will change over the life that you own this property...and that's where the 50% rule comes in...it says that you will average out bout 50% of gross rents each month on vacancy, maintenence, capital repairs, management, advertising, legal fees, etc etc etc....also 6% for management sounds low, but i'm not familirar with your area...if you're receiving 3400/month in gross rents, 1700 of that should be set aside for taxes, repairs, managemnt, etc...the other 1700 will go to pay your mortgage...doesn't seem like a deal to me

No reasonable seller would try to convey a property advertised as having a garage without the doors.As others have said, this isn't a big deal except for you should not be the one who gets stuck with no doors.

@Jay Hinrichs looking back it does look  a bit like an advertisement, LOL.

Expect to spend about $3K minimum before even cashing a check (Dues, fees, signage, advertising).

I would venture that most who try REI never get as far as you two'The problem may be that right now instead of having the worst house in a great neighborhood you have one of the better houses in a poor (or better stated small) neighborhood.Is your agent advertising outside of your local area? 

What is the best way to advertise a rental in Southern California?
