how many investment properties do conventional programs allow?

Most up to 10 including primary but their may be some that don't have any restrictions on total, only max with them.

Team Best Mortgage Option gives the correct maximum of 10 including primary, while some lenders still do not allow that many.

You're allowed up to 10 financed properties.. however, most lenders have additional overlays that limit you to 4. Also, you'll find it difficult to get a lender to allow you to finance more than 4 with any one lender.. example: 4 loans with Acme Mtg Co, 4 with XYZ Mtg Co, and 2 with ABC Mtg Co. would be acceptable with most lenders who allow up to 10 financed properties.. I hope this helps.. .. I'm a Broker here in Scottsdale AZ and I only lend in Arizona.
