Putting cash to work instead of sitting in a savings account.

Honest opinion - this seems like a great opportunity for you with 70% LTV at 5.5% for a property this type/size - I would be very very careful if you need to get the other 20% as a relatively new investor - someone willing to lend the remaining 20% could easily take advantage or come up with terms that could cost you - definitely depends on the further info - but tapping the equity of your current rentals and taking down the full 30% equity stake in this acquisition would probably be the best bet

Doesn't matter to them what they get for it or the fact that it can sometimes save them money.

A local credit union also mentioned something called a "savings secured loan" which can be used for anything (even going on vacation), but I don't know if there are tax benefits to that and I don't think I can do that under an LLC.  

Do you have a current need for that cash flow generated from the tax savings?

@Devanand Ramachandran you're trying to save pennies, but will lose dollars!

We def have some McMansions that could be remodeled to add a second unit and this would save infrastructure costs.  

Do a search and you will find a ton of info on that topic.Personally this is not something I would do.

Thank you for the info!
