@Andrew M. yeah, if you opened a HELOC while you opened while living there then it's likely that they don't want to extend that current product.  

It depends on what type of experience you want to have.

Or you’re not budgeting for a great product and will be obsceleted in the near future.My team provides all the above without hefty consultation fees like many STR experts/gurus do.  

First is, how much is needed to cashflow and what type of area is the property in where it could appreciate.For example, lets say you need $100,000 down payment to get it to cashflow $200/mo.

I'm out of Lansing, MI and we are a great market for cash flowing, $150k - $200k type 2-4 unit properties.

If anyone has an experience it would be great if you would let me know where you are developing, what type of development, as well as your experience throughout the process.

Scott's book on estimating rehab costs, it's a must read in this area: https://store.biggerpockets.com/products/the-book-on-estimat...In addition to that, I would check out my article on due diligence.

What type of insulation material are you going to be using?

The best way to estimate expenses is experience and knowledge of your specific asset type and market.For vacancy, that will depend on your market and the quality/desirability of your type of unit.

If someone wants to purchase a 3 or 4 unit they can use the Fannie Mae conventional 5% down product that came out a little under 2 years ago.
