(Typically, the MF properties I find for sale are where the owner has lost control of the tenants and just wants out.)As part of my pro forma, I build in a conservative percentage for vacancy in the first year after closing, as well as the cost of eviction for tenants who may be an issue. 

One unit hurts you more percentage wise than several units. 

A very small percentage have been audited, and all of those had no issues with the audit because they were adhering to the IRS rules.These vehicles are a very effective means to take greater control over your tax sheltered retirement savings and diversify your portfolio into stable and income producing assets such as real property, partnerships, private lending and the like.You do need to become educated on the IRS rules, which apply equally to a conventional IRA but you just are not given the flexibility to need to deal with them.  

The cleaners do pay a percentage of their profits to Turnoverbnb but that comes out of their back end.

Expenses at 2% and property value at 3% should be within a percentage point or two of being accurate, but income at 5% will be difficult to pull off unless you have a sizable increase or two at some point, which may be feasible as you mentioned this may be below market rent. 

How can I watch and keep track of market up and downs, interest rates, inflation rates, percentages, and all the numbers associated with real estate?

If you are looking for a percentage for doing Property Management such as finding tenants, repair and maintenance calls, and handling tenant issues then the going rate is more 8-10% of gross rent not 1%. 

I would say do an analysis and see what your pre-tax cashflow, after-tax cashflow, after-tax + loan pay down and Total Return (after-tax + loan pay down + appreciation) are as both numbers and percentages.

I'd say that a large percentage of the passive investors that I know are in your exact situation--they have capital to invest, but don't have the time to chase property and actively manage the process.

Yeah, look the percentage of houses offered currently as a short sale in your local mls....it’s probably 5% of what it was 7-8 years ago.
