If you desire better success with SFH then you need to model the same benefits you can get with MF. Buy more houses close together in the same neighborhoods, use the same materials and finishes in all for simplicity, negotiate deals with subs based on getting all your work, not just one house, negotiate better financing terms using a blanket loan on your whole portfolio with individual releases worded in, etc. With 75-100 SF homes you should be able to hire a full time bookkeeper/property manager, handyman and sub the rest out while you quarterback the team.
The biggest benefit of MF when you have enough units is that it's a business that supports itself and a lot of the savings you can get goes to the bottom line. The way large MF is valued is the major reason people want to buy it now due to being able to find a deal where you can force an increase in rents thru some combo of value add or better more efficient running of the property. With an increased NOI your MF value goes up and its independent of what any other MF complex near you is doing. You simply don't have that option in SFH when you property value is more closely tied to the others in the neighborhood.
The problems with MF more recently are that the prices per unit have begun to approach the cost for lower end SFH/town houses in many areas and it's starting to dilute the benefit MF used to have.
Without a bigger spread between cost per unit and rents, MF will begin to become less attractive as it will not have the cashflow to afford the additional overhead required to manage it day to day.
When a MF property has changed hands 2-4 times in the last 10 years there eventually not be enough meat left on the bone for the next guy to do any value add and then those properties will be selling off cashflow alone.
For a small owner it is also difficult to qualify for the financing to buy a 100 unit deal without doing some kind of syndication, which will dilute your ownership %, so you get a smaller slice of the big pie. Don’t misunderstand what I am saying here. The loans are available and the terms are reasonable but you have to qualify.
Fannie Mae basic requirements want you to have a net worth equal to the loan amount and also have at least 10% post closing liquidity. Not a lot of individuals sport this kind of balance sheet
