Many people also rent out mid term or short term to increase their cash flow and rent by the room or unit if you buy a multi unit property.

I plan to buy SFH & multi-family houses that I can house hack while I live in them, fix them, then rent them out.

Most municipalities have different mix-use categories which dictate the precise commercial use that's allowed.A few additional observations on mix-use assets and how I approach them (1) they are generally more difficult to finance than multi-family assets so expect lower leverage terms even if the property performs just as well if not better than a multi-family property and therefore price this into your acquisition (2) I focus on mix-use assets where at least 80% of the income is generated through the residential component.

I'm particularly passionate about small multi family. 

Even if every Concrete crew was "legal", wages would pull them to other low paid laborer jobs such as landscaping, house framing, meat packing, etc, causing wages and cost to go up for new Self Storage Construction, let alone availability.Security Systems- yep sourced overseas, China.Interest rates going lower, but I expect Inflation to go higher.

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

I am focused on small-multi fam (selling, buying, scaling).

So this is what I want to do and then build my own systems/sales team.Any advice or experience is appreciated.

PRELIM LAND PLANNING- do a preliminary layout, please remember stream buffers, specimen trees, ANY jurisdictional waters (its a good idea to have you county water systems guy come walk your property with you to verify any jurisdictional water systems and what the required state and county buffers are for those systems).

Once you're able to analyze the existing condition of these 6 systems, you can then source piece rate pricing from sub contractors or a GC -- this may be done by quantity, day rate, etc.
