Current LTV is around 50%, so the LOC would ideally be 65%-70% max LTV at least.  

If you can a detached duplex is ideal option as the rent on the non owner occupied unit will help your income qualification.  

I would like to know how to buy a home that I can realistically afford, ideally in Central Florida – either Volusia County (North of Orlando) or Pasco County (North of Tampa).

The higher taxes aren't ideal of course, but the tenants pay a higher rent and the taxes are accounted for in those rents. 

I find just like you the tenants stay longer and I deal with less nonsense calls and maint issues than I did from my multi family.

Personally, I pay out of my pocket for all of those up front and recognize I am at risk of losing all those funds.If you do not have the cash, you would need to find someone that wants to partner up with you, ideally before you put in an LOI. 

This is why 7 year auto loans are a thing and it scares me. 

I am not saying articles are bad, but you do NOT focus on articles.2 things you need to focus on.1) your website needs to resonate with your ideal traffic.2) you need to be sure your ideal traffic can quickly see you are credible.

Hi, I’m a newbie to NNN. Looking for consistent cash flow on the invested cash. What’s the good cap rate range? What is the current interest rate on LTV 70-75%? I’m focusing on restaurants for now.

Ideal, look to buy something dated, fix up the unit you're occupying and then transition renovations into the other units as the tenant leases expire.
