At least to me, it's easier to calculate net profit like the author of the article does and base my analysis off that number, where I can clearly see how much of my net profit is in equity and how much is in hard cash.What are your thoughts on the pros and cons of analyzing a rental property with the way it is done in the article?

With the purchase price so sweet I was able to go a little more upscale and modern on the rehab to force approximately $50k in equity right from the start.

If you consider at a 10% opportunity value every 100K in equity is worth $866/month and you deduct that off the top of your rental income you can see how equity decreases cash flow rather than increasing it on a property.

We currently have about 100k in equity and I would like to use about half of that as funding for our first investment. 

Then we watched and waited, the price was lowered, we re offered and got the property and ultimately added 40k in equity.

lolMy wife (partner) and I have about $175K in equity in our home and plan to take out a HELOC for I imagine what they'd allow for, $125K or so... these funds will be used to build the Tiny Cabins which I've found a source for and estimate to be $35K each to build.We are searching for and have found lots in the area we like that are close to attractions, subdivided into 3 parcels and have no restrictions, so that each lot can accomodate 3-6 Tiny Cabins (1 or 2 on each parcel).

In And the permutations of that phrase Before you make your move.We owned more than a dozen rentals in equity trust self directed I are a and we hated it so much so we spent thousands to move the titles and move the rentals to a different custodian.

With around $300k in equity though, that capitol will likely be better invested elsewhere. 

So with the LTV and your example, if I find a property for 100k, with 50k in renovations, and it appraises for 200k, would the "extra" 50k just be in equity in the property?

This way I would have a lot of build-in equity kept in the property.
