Where are you finding most of your tenants, and how much time/effort is required to secure a tenant?

While you may be able to get away with not informing the county about the change in residency status, most of the legal residence application processes in SC counties to change your assessment ratio from 6% to 4% will require you to disclose if you currently claim this status elsewhere.

The strange thing though, is that the MLS shows the home to be 1,895 sq ft even though the sunroom is heated and cooled, and attached to the house securely, with windows (this sunroom is an amazing add-on and in great alignment with the rest of the home compared to other sunroom mods I’ve seen).

It's been steadily going up however, so I'm either looking for lenders who would do a HELOC once my credit score reaches the required number OR I'm also seeking private lender who would be willing to lend with a second position lien on the property for the renovation amount ($35k-$40k)I was working with a private lender but he proved to be unprofessional and not able to prepare the proper, legal documents.

What LTV is required?

A HELOC cannot be used as Reserves or assets and PITI assets are required when you buy more REI.When you look at the blended rate having a HELOC and a 2% rate again it usually causes a higher payment over a simple refinance. 

I use Hocker Title -- they do off-market through the regular title process, but if something comes up that requires an attorney, there are attorneys on staff who can work through the issues. 

Start small and work your way up as you build comfort and confidence in your skills.Although not required, a real estate license can offer beneficial networking and educational possibilities for those who engage in real estate.

The CCIM designation is a big plus but not required.
