Hi if I am going to buy and investment property , put it under an LLC, what are the pros and cons of using a saving secured loan vs. delayed financing?

the only problem is that the banks don't want to loan on it because it is pre 1976  I don't mind buying it cash or with some hard money. 

Yes it is factored into the loan and you are paying for it so you might as well use it.

But I captured equity at purchase then more quickly through value add then refinanced into long term loans before the balloon.

Different loans, different lending standards, etc.

This could be middle aged couples looking to downsize, young adults looking to be mobile and save some cash - especially around this rental market in Denver- or people who may have been in some financial issues who are finding it hard to be approved to rent or get a loan, etc... 

Rest assured that you don't need to bring all cash to the table on a fix and flip and we can assist you in closing the loan.

Coventional Loan

The single payment will cover both the original loan amount and the additional cash-out amount.HELOC might be better if you need intermittent access to funds, while a cash-out refinance could be more suitable for a one-time need with a clear purpose.

Or do the lenders require that I establish primary residence first, before getting an fha or a fannie mae loan for a primary?
