Woah!
If you put $45k down and pay $500 per month negative cash flow --- you are not going to be too excited about your real estate venture in 6 months...You won't feed any better if your negative cash flow was $300 per month.
After doing all kinds of rentals for 50+ years in Northern Calif, I realized long ago that negative cash flow and "crossing my fingers" hoping for appreciation was not good foundation for my planned real estate empire.
Well, like you, because cash flow was most important to me an most newbie investors, I had to have a plan. 50 years later, and 250 rental homes, at my high mark, I will tell you what I did and why it worked..
I buy groups of homes on a single parcel, usually 5 or more. These will always be in old parts of town, not subdivisions. Ideally in need of repairs and better management and NOT in war zone areas of town.
These groups may be a combination of small houses, duplex, triplex, mobile, conversions, etc.
Because they are 5 or more units and run down, the banks WILL NOT FINANCE THEM. The banker will run if she sees you coming into the bank. The sellers know this and will almost always offer seller financing on these type deals. You and seller make your own terms.
By the way, over the years, when I sold, I would ALWAYS OFFER the buyer seller financing with very good terms. For a number of reasons, no taxes on the big sale, I can sell at higher price because of my terms. (I don't want the new buyer to give me back they property so the max the monthly payment will be is 50% of gross rents). Win-win.
Bonus: many, many times I have gone back to the holder of these notes on properties I have bought and asked if that holder would take a discount if I paid off his note with cash. The usual discount I get is 30-50% off.
Because I fix these units up and because the rents were low to begin with, I force up appreciation almost 100% in about 2 years. I control this appreciation...I don't sit on my couch and hope for it.
Find someone to help you on this. Do some google searchs....Buy that $245,000 duplex when you are at a different stage in your investing, not now when cash flow is so important to you.
Let me know if I can help.
