For instance if they sold their old property for $300K and were buying the new property for $400K your client needs to take title to at least 75%. 

Hello BiggerPockets community,I'm having some confusion with standard practice for 'First, last, deposit' collection in the scenario that the first month will be prorated.Say for instance: My property has a rent of $1000 monthly with a deposit of one month's rent ($1000), and a targeted lease start of the 15th.Given that rent will be due on the first of every month, what is the amount which should be collected for the initial 'First, last, deposit'?

Any other suggestions on how to prevent these instances from reoccurring short of having them apply before I show the units?

For instance. 

However, I can’t condemn a method of financing that has proved successful in many of not most instances in allowing participants to accomplish their goals because it’s being misused by some disciples of irresponsible real estate “priests” 

In this instance, an appraiser may assess the Cap Rate of the Starbucks to be 5%, while the mom-and-pop shop is assessed to have a 10% Cap Rate.

(There is also the multi-family house-hack where you buy a duplex, live in one side and rent the other, but A) those are harder to find and B) the numbers don't work as well as rent-by-the-room.)So for instance, in Denver or Colorado Springs here, house-hacking would be buying a 4-5br home.

If you are in the smokies for instance and don't have a hot tub, you will be below average.  

For instance, while it can bolster initial cash flow by reducing tax liability, it could diminish deductions in subsequent years (when the property might produce better cashflow), impacting overall tax footprint, so you need to take into account all that in the context of your short term and long term tax strategy (e.g. if you plan on selling soon, at which time the depreciation gets recovered, or not and planning to hold for a long term/forever/1031, buying more later and creating more depreciation to offset cashflow or not, etc.).The alternative is a do-it-yourself (DIY) or survey option, which costs around $400 to $500 per property (I can do my CSS report in 10min, once I have all the data needed).

In many instances like this one - by the time it gets investigated damage is already done
