Lender suggest pay off rental property with my house equity

[Paulina Espinoza]

Looking for my first small multifamily rental, my lender has suggested me to use the equity of my house to pay in total the SMR and therefore just to have a mortgage on my house. Is it a good idea?  And then, since the SMR is going to be paid off, get another home equity loan -since duplex, triplex and quads are considered residential property- to make down payments in more SMR?- Thank you,Newbies in long term buying and hold.
