@Soli Cayetano is as sincere and honest as they come. 

Should I put down the bare minimum (3.5%, if I'm not mistaken)?

we were only 10 days over schedule (we allocated just under 2 months) which is remarkable considering the various issues we encountered and the size of this rehab (we removed 4 walls (including a load baring), added 1 wall, added new bathroom, redid kitchen and existing bathroom layout, (new locations on shower, toilet, and vanity) removed a door, added 2 windows, new flooring throughout, and added an eyebrow porch.  

Most of my tenants stays for years so there’s barely any work or turnovers.

Deal- your looking for a property that has a large RV/Vehicle/Boat storage portion, or extra bare ground. 

The solo 401(k) is one of them. 401(k), 403(b), 457(b) are also QRP.

. $25 barely feeds a family of four a cheap meal.

That is why you should, at the bare minimum, understand multifamily deal analysis, also called "Underwriting."

I can barely get firms to look at columbus with 10x years of experience thats mostly for ground up. the average house cost is still less than 100k which means you have a lot of houses to tear down still to create a housing shortage. the economics don't make it favorable for any type of investing but turn key or maybe ground up in the urban core which works in any city. but compare any of these cities, I'll take Indianapolis, Chicago, Minneapolis, and columbus and Milwaukee and pass on the rest. 

Directly to your distribution question: you can have one or more per LLC, and that depends on multiple factors:- property class - you might not want to mix A class property with a D class property in the same LLC, due to different tenant level- cash flow - you might want to keep your cash flow cow separate from the ones that barely produce- equity - you might want to keep the one with large equity in its own LLC while you can group the ones with little equity in another LLC (let's say you have one with 50K equity in its own LLC and 3 other each with only 10K in another LLC, till their equity grows to your risk threshold when you move them out in their own LLC).- number of units (in the case of MF)- location of real estateThe investor has to decide what mix is optimal for their situation.4.
