As long as you are doing regular inspections (quarterly) and doing repairs immediately billed to the tenants turn over costs should usually not amount to any more than paint and minor repairs.The key is never leave repairs till they move out, that is way too late. 

As far maintenance, I think it may be best to get a handyman on board which can do various things on the property on regular basis.

Set up your voicemail like a regular person and respond to it.

Regular HOA fees are deductible, but not HOA transfer fees.

Most people pay the IO option and after 2 to 3 years the IO fees ( interest only ) were more than if you just did a regular cash out option from the start.I prefer a cash out refinance over a HELOC but if you do the HELOC please make sure you have a plan to pay it off quickly or you will regret it.

I also appreciate the fact that they offer regular 20% discounts with webinars and have the added bonus that you lock in your price for life.

As a regular w2 employee, a general rule of thumb is you will be paying 1/3 of your income into taxes.

I find people assume that VA and FHA repos are a bargain, when actually the starting bid price would be a good market price if they were for sale as a regular home.

Now I connect with Realtors on the ground that know the neighborhood well, I also always ask about their network of Property Managers, number of General Contractors in their network (so I'm not waiting for a GC to finish one job before they get to my property), if they regularly deal with Out Of State Investors, etc...    

Commercial leases of free standing buildings are usually triple-net (NNN) .Commercial leases are also usually longer 5-10+ years and include regular increases in the lease.Check with your insurance agent to see if you need a different kind of policy.
