Has anyone used bridge loans for this type of strategy or is there any other loans that anyone would recommend other than HELOC?

I never make a loan, no matter the equity position, that the past actions of the borrowers lead me to wonder if they will be likely to pay me back. 

If you’re not paying cash for properties, get pre-approved for an investor loan to understand your available credit.Time FrameThe shorter your timeline to achieve your goal, the more upfront capital and credit you’ll need.End GoalMost investing goals focus on replacing their current income, like $5,000/Mo.

I’ve also taken out short term loans (1-5 years) to use as my 25% down payments.

They are bought either with SHORT term high interest (hard money) type loans or purchased in cash.

There are 10% SBA loans to purchase businesses.

There are some that are great for sure, but I have currently heard terrible stories about people putting money in the last 2-3 years and losing it all, capital calls and losing the whole deal due to bad bridge loans (some coming do very soon). 

My guess is if you can make the interest rates work, there will be dozens of these available in about 2-3 years when the loans start maturing.Good luck and best wishes.
