I would say the difference is largely a question of which is the better interest rate - the heloc vs the rental mortgage.  

We're looking to sell our rental property that isn't performing well.

I used it as a down payment on my first rental property and had no issues on either side.

Hi BiggerPockets Forum,      I am looking at purchasing my first rental property.

There are a couple factors with Modular construction, one is geography, some places Mods have the same value as site built, other areas they tend to have less value, I currently own 3 modulars as rentals, and have flipped, as well as Listed a few for banks.

You can't take depreciation deductions on a primary residence.I have a feeling that converting this rental to a primary will also unleash a huge tax bill in the form of depreciation recapture. 

We are looking to purchase our next investment property to buy and hold as a rental.

That leaves you with a good chunk of change to start the business and grow from that point with rental income/passive income coming in each month.If you have any specific questions and want to talk about Pinellas, Citrus or Hillsborough reach out I always enjoy talkng REI.

Open to any advice from the experts on how to increase traffic as the house would be a great investment for a first-time buyer or to add to a rental portfolio! 

I probably going to use them for equity financing on a rental property that is paid for.
