So I did a 3-2-1 buydown and secured a 2.875% interest loan for the first year of the loan, and it will gradually go up a percent each year until it hits my rate of 5.875%!

Do you currently work with an expert CPA who is helping you maximize tax breaks with your real estate investments?

Quote from @Jordan Kaylor: I'm new to real estate investing and have secured a HELOC on my existing home.  

You may want to work with an experienced contractor and/or other experts who have done this in the past.Disclaimer: While I’m a licensed attorney, I’m not your attorney.

Even if you manage to find an office with an existing tenant, their lease could be approaching expiration, and without plans to renew, it can take an incredibly long time to secure a new tenant for the space.

Start small, build a reserve fund, and work with local experts to ensure your first investment is a solid one.Good luck!

Educate yourself, become expert, then make decisions from a place of expertise.  

But I also understand some people don’t really care about the cash flow as much as the security of not having to worry about a vacancy or whatever.

In both cases to keep things clean for underwriting at the bank I used my HELOC to secure the mortgage. 

You will receive the security deposit in Checking but then transfer it to Savings.Savings: Hold the deposit here so it's separate from operating funds.
