There is no reason for any individual to have a computer in their home. - Ken Olson

I've seen this bite numerous individuals that are new to new construction multi-family.  

Remind your investor clients that you're not making a lot of money off of their individual transactions, so you would like them to send you their referrals for Retail buyers.

Yes they are multifamily, but usually individually owned.

@Hank Thomas it’s common for them to start with a “desk top appraisal” (at no cost) which means they will pull from their data source to get a valuation (usually very conservative) without going to your property.

I know an individual who paid 657k in taxes last year because he had his property in S-corp.

@Lydia BarIt depends on the level of experience the individual has with both and the type of loans you need to get. 

Main challenge is the impact to each individual's DTI as we'd all be carrying a "second" mortgage when it comes to any other loan application.

Obviously, much of the following is dependent on the individual, but non-owner occupied investments can be in the 3-4% range (this rate can even go lower if it is owner occupied!)
