18-- Beginning by building on free land.

[Tanner Johnson]

I am 18 years old living in a town of about 30,000 give or take. Grandfather is decently big in the rental business and he very generously gifted me a lot located in a lower-middle income area. Lot is 168x150 (feet) with a little house generating 400/m at the moment and the lot+home is valued at about $55,000. I actually took a loan on it but I am just keeping the money to pay back to build solid credit for future real estate business. The lot is easily capable of holding 2 residences. So my plan is to build 2 symmetrical single family homes doing almost all of the work myself (Holding general contractors license, and very capable in housebuilding grandpa  that will help me every step of the way) and this should keep cost well below what the houses will be worth when I am finished. This is definitely something I am looking to build off of, he has other lots capable of holding houses in which he has no intention of building and is very willing to help me through everything. I currently do not have much capital so will likely be doing a lot of banking. So my question to you guys is, is there anyone here who started their portfolio by building themselves and then renting, if so, what problems did you run into? Is there anything that i am not considering that I should expect? I am new to the business and I am so thankful to be blessed with the opportunity my grandfather has gifted me and I really want to do this right so I can grow my portfolio quickly for more freedom in the future. Any input, advice, recommendation is welcome, and I thank you all for any help you can give. Excited to learn. This seems like a great platform.
