I'm still trying to get in contact with the park that is near to get their monthly lot rate. 

The tax advantages of buying/holding gas stations are pretty great.Many of the components of gas stations including pumps, tanks, external parking areas, and other equipment are classified as either 5 or 15 year property so you can bonus depreciate a lot of it (minus the land value) and get significant deductions in year 1.With the 2025 bonus depreciation rate at 40%, a $1 million gas station acquisition could still lead to $100K+ in year 1 deductions depending on the specifics of your deal.

Then they give you a random login/password for that site that you'll never remember and can't change.  

Quote from @Bob Dole: All,Apologies for the newb question, but I just heard about cost segregation and have been reading up about it online.My understanding is this (and please correct me where I'm wrong):Pros: -accelerate depreciation, front load (vs. just a straight line over 39 years) -save money on taxes because of the depreciationCons: -if I sell the property, the recapture will be larger -not recommended if you flip propertiesSo hypothetical situation:-Majority of our income is W2 based, let's say it's $500k-Net income from commercial rental is $100k-Income from dividends and interests is $100k-Both of us are full time W2, so non-prof real estate (but this can change  -- please see below)So we're hypothetically grossing $700k a year. 

It's pretty east to get into the 20% long term capital gains rate and 3.8% Net Investment Income Tax. 

It seems duplexes are valued on rent rates for the most part.

You could also get a line of credit for about $150k (you should be able to borrow 75% of the value.)The reason I suggest this is…1) you save $40-$60k in selling costs. 2) you have a lower blended interest rate (2/3rds at 3.25% and 1/3rd at 7 or 8% instead of the whole $500k at 7 or 8%) saving you another $1k/mo in interest. 3) you only pay interest on that $150k when you actually use it, not from day 1  Unless you hate this property, or want to buy something you can’t afford without selling, that would be my plan.

And, analyzing ROI, CoC, and rent vacancy rates, etc are all manual. 

Or put in your interest rate here, and your loan balance there.The art is where I think most people struggle, and I don't think this can really be done without real world knowledge.
