As an active real estate investor I can tell you it’s going to be hard to make $300k a year and not divert time and energy away from your day job.

@Joel Owens thanks for the advice. flip is unsecured. this is in the single digit percentage of net worth, so I haven't put as much energy towards this, but still needing to come to a conclusion. 

Portfolio loan via a single LLC is your most cost efficient manner.

@Scott PassmanIf the point is that you don't need to do courses in REI to make money in it, sure.If the point is that college is really not the best place for types that can handle self-education, sure. even Elon Musk has repeatedly gone on the record to insist that he's a better rocket scientist for having two BS degrees in economics and physics and then dropping out of a PhD in energy physics, and a lot of people he's hired agree.But the reality as I saw it in my former profession as a teacher is that most people suck at self-education, suck at a nuts-and-bolts level on the tools of autonomous learning, research and analysis, suck in general at doing anything when someone isn't there holding their hand for them and patting them on the back every day.

I've never been to such a quick and efficient closing; I barely had time to drink the coffee they made me.

The land would have to be a sweetheart deal, IMO and you'd have to know that the pain, time and energy you're going to expend would be relatively equal to co-investing in a larger play or bringing together other investors to do a larger value-add or development. 

Need more detail as there was court case classifying the solar equipment as personal property, not real property2) You might be able to get Business Energy CreditMight be worth talking to Tax professional because credit can give you significant tax saving as credit decreases your tax dollar for dollar.

The issue is when the bank went to the an appraisal, there is only one water  meter in the property and they are saying it is technically has a use code for single family, most likely meaning that the efficiency addition to the home was done unpermitted.My realtor is talking about telling the home owner to open what is currently a permanent door and removing items from the kitchen and having them redo the appraisal/application as a SFH.

But if the project size is like 50-100 residential units on top of maybe 10k of commercial, I'm wondering why that wouldn't be cost efficient.
