If even just a quarter of them are removed, don't you think it would greatly affect housing markets?

Investors can invest through 3 paths where investors capital is deployed immediately and stays deployed. 1) Our unlevered debt fund that targets 7-9% return with a liquid portfolio and quarterly liquidity.

If the number is in fact 10% I would not change that number in your calculations.These numbers on vacancies change quarterly, so your numbers should reflect the changes.  

Regular maintenance updates from your property manager—such as quarterly reports outlining requests, costs, and resolutions—can also help you stay informed and track spending trends over time.Building relationships with local contractors or networking with other investors in Cleveland can also be valuable.

For my account I pay $10 per quarter while the loan is active so only $40 a year to borrow this money. 

My Team hosts 12+ Free meetups each quarter in Massachusetts, New Hampshire, and Maine, under the name Simplified Real Estate Meetups.

I am mostly interested in appreciation/pay out at the end rather than cash flow each quarter.

My approach is to take a few minutes per quarter and make sure it is accurate by manually checking my true competition and adjustmenting prices accordingly. 

The fourth loan offer ask to deposit the whole loan amount into a CD.
