.), is the lot infill, do you need to re-zone, are water/sewer available (if not, get a soil scientist to test the soils), impact/tap fees, etc.

Including myself, there are only two of us agents underneath him.

Usually the State has clear guidelines on this and you don't want to be held responsible in the event of soil contamination or environmental hazards to the property or the property owner could come back afterwards on this issue.

It is my choice as a guest to respect their laws on their soil.

I live in the same neighborhood and know that shifting soil is common in MS.

There aren't wars on our soil, mass famine, mass disease, or other visible crises.

Never had an issue, you have more likelihood of the cabinets underneath the granite wearing out long before the counter!

I'll be honest with you:it sounds like you're attempting to dive into two separate business at the same time (selling solar panels & wholesaling houses).This is a huge entrepreneurial no-no.If you're going to get into a new business, your attention should NOT be divided.That being said, if you've $25k to spend, the best thing to do with it, is nothing.Not completely nothing, but spend it on ListSource and Skip Tracing.It's your business, you need to lean into it.Take the list and cold call it.Talk to homeowners, get comfortable being uncomfortable.You need to make offers and fail forward.After you've a deal or two under your belt, I'd recommend hiring and training (local) Americans to cold call for you.You'll get no greater ROI than this :)As @David Lecko said, enjoy your trip and hit the ground running once you're back on US soil!
