You don't need to, especially on deals that just make sense, but it's a good inclusion if you already have your underwriting model in Excel or gSheets because you can use all those variables, once filled out, to auto-populate various Sensitivity/Stability Analysis charts.Here's what I have for Multifamily/Rentals (all auto-populated from the model):On Fix & Flips, I only include the ARV Stability/Sensitivity Chart (this is the entire model, stability analysis at the bottom):Since having these built out, it's something I mostly just glance at after underwriting to make sure everything looks good.

In the past, these sources have been pretty reliable when I'm looking to get a second opinion for market insight and analysis as well as a source of referrals. 

I think 50-150 units is no mans land and we stick to institutional level sized deals. his underwriting is too simple. the unit mixes are off we only build studios and 1 beds for fast absorption, the deal is also under parked without a parking study. anyone who uses "roughly" in their analysis isn't sophisticated enough. we underwrite rent growth, asset growth, and a million other assumptions this wouldn't pass any people I know who invest in deals. get with a More experienced operator and read more sophisticated underwriting. 400k per door new construction is crazy. how much is the land? 

make sure to look at other development analysis don't just buy a site 

I have had analysis paralysis.

Regardless if you have skills in finding deals or have access to capital, without a good network, you won't close the deal.I agree you need a good network in real estate, but my issue with this belief is that too many aspiring investors get caught up in the networking process and spend little to no time developing actual real estate skills (marketing, sales, negotiation, analysis).

The assessment evaluates the home’s energy efficiency, and conducts analysis to asses the potential savings for a variety of improvements.Cost Effective Test for Newly Constructed HomesFor newly constructed homes, the improvements are cost effective when they exceed the standards set by the most recent International Energy Conservation Code (IECC) that has been adopted by HUD for new construction properties.

And I'm currently building in the area) Do a market analysis to see what has the highest rent vs cost to build. 2 bed units?

Do a deal analysis and see if it works.
