@Alexander San talk to lenders, talk to credit unions, get an idea of what your leveraging abilities are so that when you look at a property, you can accurately assess cash flow. When you're young, you want to make sure that your money is going to continue to grow and you want more coming in rather than feeding or paying to sustain a property. Learn the difference between adjustable rates, versus fixed rates, private money, and seller financing. Rates can range from as low as 3.5% to north of 10% based on where you get your money from and on a loan of $500,000 which could mean $1500/month to $4200/month or more. That will dramatically impact what you determine to be a good versus a bad deal. First and foremost, learn about the money that you're getting.
Next, learn about construction costs. I had a client buy a house recently thinking that the cost to fix up the property would be significantly lower than he thought it would be. He's happy where he is, but his property is costing him every time he turns around whether it's actual remodel costs or just furnishing the property because it's his personal residence. There were a lot of things that he thought would be minor that turned out to be more costly than he thought they would be whether it was scraping ceilings, creating a flush ceiling, raising a roof line, changing a door, it's added up and been more complicated than he thought.
This game requires doing your due diligence especially in Southern California where the swings are still fractional, but when 25% is $250,000, it hurts when it goes south. Like I said, if you have more questions and would like to talk, PM me and I'd be happy to continue the conversation.
