If you don't put any cash in, you can't measure how  quickly you get it back...there is not "it".Percentages don't measure everything in REI accurately anyway, so there's no need to search for one to measure the quality of the REI. 

Many landlords (managers and owners) stated that they had much lower expectations for what percentage of rent they expected to collect in April and were pleasantly surprised by the results of their rent collection. 

We had a very significant number of leases up for renewal in the next few months, many including rent increases of various percentages.

All-State is refunding for non-use of cars by a percentage for their customers. 

Keep in mind, if he is enough of a percentage owner in your LLC he'll likely have to provide all the same docs that you will for the loan.

In terms of how much money you should save up, if I were you, I would take a look at the local real estate inventory that you are interested in and save a percentage of that. 

I feel I may be estimating these costs incorrectly, which is throwing off my Cash on Cash ROI percentage in the models.

It can weed out the properties that don't at least break even in cash flow.I would think that there are many variables that would have to come in to play, such as different down payment percentages, adjust with current mortgage rates, rent estimates, quality of property/amenities, etc. 

Because the percentage of ownership in these properties is different, I have three LLC's created for the properties.

What percentages do you get on these options?
