May be in Texas it's a good way to make money.

You can pivot, but if you are trying to do due diligence on how flipping, BRRRR, STR, and syndications would work for you, you will likely get stuck in the mud.Don't think that if you spend three months learning about flipping and decide the numbers don't work for you, you lost time.

I lend money privately and would never consider this as it is dependent on things out of my control (permits, neighbors, you being a good host, rental demand etc) I sell a ton of STR that are in actual resort communities and have great amenities and they are all  competing for the same guests, I can't imagine that there is a need/demand for this type of unit.

Make sure you are, in fact, spending less on a monthly basis than if you were buying/renting an equivalent personal property.

If you are raising money you will need to register the exemption with the SEC, and it will depend on whether you are using accredited or non accredited investors. 

Quote from @Damein White: I’m thinking should i add mini split to my properties but will it increase my home value  No, waste of time and money. 

If I pay with cash it will take up most of my money that I have set aside to perform renovations on the property.

If you want to spend the money, you can split the water. 

You're going to work for this money, you can be sure of that. 

This kind of doesn't make much sense since something under construction is not going to have cash flow - I'd check out hard money or "ground up construction" private lenders
