Now, I'm looking to venture into real estate investment for several reasons:Diversify my investment portfolioBuild generational wealthLower my taxable incomeMy Investment Criteria:Buy and Hold Strategy: I'm focused on long-term investments.Cash Flow: Not a priority for me; I don’t need the income from these properties, even in retirement.Acquisition Pace: I plan to acquire one or two properties per year.

Purchase price: $350,000 Cash invested: $20,000 I was able to get a 3.75% interest rate in a time where rates were at 8%.

From what I have deduced from your response, there is no need for overcomplexity as long as I do not pierce the corporate veil. 

I keep seeing folks touting these data centers.. keep in mind for the subs building them there is money but long term they employ very few people and do not have a big impact on RE or RE values long term.. just  saying..

i'm skeptical that it will 'cash flow' $400-500 a month if you're using a HELOC for the down payment. 

If you can get one which cash flows it would be worth it.

But as a short-term solution, playing the 0% credit card game can be an option, but from my experience, juggling from one to the next with no backup plan often ends in paying high interest in the long run.

Read the Bigger Pockets Book by Avery Carl called Short Term Rental, Long Term Wealth!!

As long as you are both on title, I don't think it is a problem-but ask the bank. 

If you are a centimillionaire, legacy holding parks cash that has few other places to sit.
