Evaluate your savings, income, and outgoings; moreover, educate yourself about mortgage alternatives and programs that help with a down payment.

In the past I have asked for a higher deposit but I just dont want to deal with any potential non payment issues nor evictions. 

Especially for a tenant who has never done anything wrong in the first place, not even late with payment.

My current home loan is a heloc and its pretty much maxed out from using it for a down payment on the first property and its also climbed to 9% so I  need to get it redone to a traditional mortgage and get the rate down on it.

Even then you need a business license if you are collecting any kind of payment for it even if it is your place.  

So, if Title is held by the LLC and the mortgages are under your name, who makes the mortgage payments?

Is he current on his payments?

I was running some numbers and it seems to me that when you're doing a BRRRR you have two choices: you can either pull a lot of money out in the refinance, which then helps you scale up quickly, but then you leave yourself with a high mortgage payment, and little to no cash flow.

Avail is more limited to the tenant experience side of things such as creating lease agreements and accepting rent payments and deposits.

A 15 year mortgage requires you to pay whatever the monthly payment is with no flexibility, with a higher payment.
