Check with your lender what your new payment would be on the existing and what that would allow you to afford on your next purchase.You can still do an owner-occupied loan up to 4 units but if you're using your FHA/VA loan you'll have to go conventional 5-10% down. 

@Moss Siridajnawanan send the tenant a Notice to Terminate Tenancy, or whatever your state version of this NOW.Typically, you can put the end date of the lease in the document.This is a legal document that tells the tenant you do not want to renewal their lease and also allows you to start eviction process the day after the lease ends if tenant does not move out.

Based on income, a tenant may only get partial financial assistance with the rent, some may get their rent paid 100%, some get an allowance toward their utility bills. 

Refinancing can allow you to pull out equity, providing you with additional funds to use for the down payment on a new property.Look into financing options for purchasing a duplex.

I stay away and do not allow the 5 piece vinyl sets because the seems fail.  

You can probably get a bank account set up that will allows your tenants to make rent deposits. 

I’m gonna be totally honest with you, it’s extremely hard if not impossible to replace a full time 40 hour a week with rental income at least in the shorter, it’s the type of thing that helps you retire a little early and have a buffer in retirement, my grandmother has been in poor heath for years, those properties have allowed us to give her the best care possible, if you don’t already own a home and feel comfortable with your budget and the ability to live in that house for  at least a few years, I’d get started on that don’t even need to over complicate it, find a budget, find a house you like and can see yourself in at least for the medium term buy it. 

Depending on where you are there may be conventional products that still allow you to put as little as 5% down.

Real estate professional status is valuable because it allows us to reclassify these rental activities to active.

The HOA told me that though that's a bit low, they will allow it as long as I use area rugs so that 80% of the unit is covered by rugs or carpet (I have carpet in the bedrooms).
