Forgive me if you addressed this earlier, but you have to actually have equity in your primary residence to use in order to get one and then depending on how much you have it may not be that large and that's IF you qualify. 

Maybe for large apartment buildings that will make sense but for 1-4 units I don't see the need to request a seller's tax return. 

Is the house on a large lot? 

I’d like to scale and continue to buy and flip or buy and hold more single family properties or even multi-family properties.

That said, there may be a market or two, here and there, where solar is actually a thing that can be measured on a market scale, rather than an individual scale.

Re laundry money, i never include this in my calculation - i simply look at it as bonus income. your vacancy at 3% sounds low, again not knowing the location its hard to sell. 5% would be my lower estimate in high demand location and proven 100% occupancy in the last 2-3 years.Repairs and maintenance, unless the property was recently renovated top to bottom or you would renew the large items like roofs, HVAC, water heaters etc 5% and 4$ is tight. 

Yes a large majority of Port Arthur is widely considered D-, but there are a few pockets that are workable.

Then re-invest and scale up until I reach financial independence. 

If you own any large commercial properties and have a question, need advice, or want a POC in regards to HVAC, I may be able to leverage his 25+ years of industry experience.Thanks again and I look forward to learning from each and every one of you!

@Jeongmin J.There are several considerations that can go into the analysis of whether you need an LLC or whether a large insurance policy will suffice.
