Developing would consist of getting your utilities lined up for the area, plotting off sections (if needed), creating roads and other ways of access, etc. and then selling those lots off to builders. 

I'm familiarizing myself with SONYMA (state of NY mortgage agency) programs and I know they require that no other properties be owned simultaneously if you plan to utilize a SONYMA loan.

The suggestion from another real estate investor who has seemed to crack the same nut is to move all addresses to where my tax address is (Kansas), have dad either add US phone in his home for me under my name or change his phone account name to my name; get utilities put in my name... 

We now have 3 tenants on a one year lease, paying 1300 total, and they pay all utilities except sewer and water (about $300 per quarter).

Make sure before you purchase the property that both homes have separate utility and water meters.

Currently, I pay all utilities unless Electric goes over $200 a month, then the tenants split the difference.

I have several investors and I’m not sure I have the ability to move fast enough to utilize all of their purchasing power.

Getting water and sewer hooked up will be expensive---you will have to have a separate electrical connection added to to split utilities. 

I'm currently househacking a 3bed/2.5 bath and I'm technically being paid 50$ a month to live in my home, since the rent is covering the MTI plus all utilities.

Do we use the banks money or utilize cash and try the BRRRR method?
