The income includes things like late fees, a rented garage, and utilities that are billed back to the tenant. 

I'm paying for what I'm getting right nowThat being said - I could pay slightly more for something where I know, or have a very good idea something is going to happen - such as road access, utility access, new developments of some sort etc Or less (probably wouldn't buy) if something bad is going to happen - railroad tracks, dump, Sec 8 housing built near by etc 

There are two main ways to utilize this exemption.

In my case, I had small bedrooms in a small house and took out the small closets to each of the bedrooms because I needed that space to create a larger bathroom, utility room, and create a hall closet that before did not exist, leaving both bedrooms without a traditional "closet".

Type of construction materials for the build(block/metal frame/wood frame), separate utilities, finishes, tech, cleaning crews, any tips and tricks would be HUGE! 

I have a vision of building and developing mobile home communities in upstate NY that are vertically integrated to allow future members to choose from a catalog of homes, have them installed, provide them with financing options, and make the process of selecting, buying, and living in the community very smooth.Since this is my first time doing this, I would love to chat with an experienced mobile home developer on the following items:Zoning - navigating the zoning process to allow the community to be allowedStart up costs - I am a finance person who would love to better understand start up costs - septic / electrical / water / pads / roads / etcOn Going Maint Costs - in building our business case, I want to build a conservative financial model to capture all re-occurring expenses - utilities, landscaping, capex, septic clean out, etc.I know this is a lot, but would greatly appreciate talking to someone who is an expert in this asset class!

Fifteen percent IRR is possible, and single digit cash on cash is achievable. 

I'd like to take a deeper dive into subject to, wraps and other related things to educate myself and see whether some of these might be things I can actually utilize in my real estate journey. 

Quote from @Fernando Martin-Gullans: Hey y’all, I’m a retail investor with 2 SFH rentals worth a combined ~$650k looking to utilize some of my stored equity to buy more out-of-state properties, but I’m not quite sure how best to proceed given that my interest rates are incredibly low (leaning me away from refinancing) and neither property is owner-occupied (which I believe prevents me from using a HELOC).

It's been great - the property is 100% paid off and the house is worth 300-340k generating approx $2300/mo (that's after utilities/management fees etc.)I'm considering selling the property to buy 3 more within the same price range in the same market.
