18 year old getting started— advice and things to look out for?

[Tanner Johnson]

My situation- I have plans to build multiple sfr in my city and have a few very generous lots in lower- middle income communities. My first project is on a large lot sitting off one of the bigger streets in my town. Going to build 2 mirrored single story 1500sqft 3 bed 2 bath houses w garages mirrored exactly lock each other. Currently the property holds a older small house on one side of the lot witch I will demolish after I finish the east side house. All building work will be done by me as I have a class b contractors license, under supervision and mentor ship by my grandfather who has built and held to a very large real estate portfolio. All building plans have been completed and approved by the City now

just need to apply for permit. Here is the financial plan, for the past year or two I’ve been buying materials when there is a good deal or prices are low .after completing my material list and hookups permits and all I should be all on for about 55k. The first house is all cash. To cedar finished I am planning to proceed in to the second through financing. And should be similar cost. I think this is a pretty safe bet even in a situation where one is vacant I will still be able to pay the mortgage easily. Each unit will rent for 1000/mo and shouldent have any problems being occupied.after these are finished I have another similar lot that I plan to do the same thing on. I want opinions, personally I feel it is very solid expecially since the first will be paid for when it’s done, but like I said I’m new to to this and only 18 so advice or things to look out for would help out a lot. My grandfather is an amazing mentor who built all of his own apartment complexes and I think it would be silly to not take advantage of his great knowledge and he is super exited to teach and go through this process with my.
