I want to start building our portfolio and would love some experienced help with direction.Over the past ten years, it seems like I've had numerous deals/ideas that just didn't come to fruition and I'm just feeling a bit defeated. 

Any model ideas?

I'm also in the process of exploring Terra Notes, but may just stick with Notion, Pipedrive, and Excel.I previously worked at a fund and Excel was used to globally track a decent portfolio (about $100m), to include limited depth loan pacing and management.

This does not align with buying most buildings in cash.Once you progress in your investing efforts you may come across more UHNW individuals, family offices and institutions who would take the lower return for limiting risk (all cash deal).

Padsplit seems like a neat idea to me, but seems expensive. 

Valuing your time and understanding your limits and skills will make a big difference in the equity you build, the quality of the work and your sanity. 

At least plan B does not sound a complete bad idea now.Thank you!

I have no idea how real these rates are they dont have credit score just A+,B+ , C+ d and e and application fee is $400.

First thing I'd do is check comps to get an idea of the demand and rates you can charge for your condo as a MTR.

Not sure it will replace GC estimation but at least will give you an idea.
