The age, size and type of property will impact your costs, but as a general rule of thumb Fannie Mae recommends that a property owner should allocate two percent of the total property value annually to cover maintenance expenses.

(chart shows: 15% vacancy in 2012, down to 8% currently)I inquired how the aboveforecast was modeled, but no explanation was available.

I usually use those with a disclaimer that the sizes, etc were obtained from them and that buyer needs to verify all info.

If you own all the properties and anyone but you will be leasing them, check your local state law but the leasing agent and your company will likely need a real estate license.Overall, for managing your own portfolio at this size it seems to me it would be easier, simpler and possibly less expensive to let a 3rd party manager assume the headaches

Once you speak with that person, just give them the basics, lot size, address, etc.

The size of the properties2. 

@Petra HarperWhat loan size are you looking for?  

You can also click on 'Browse' on the right of the search bar and you will see a big list of demographics, behaviors, etc.To select the type of housing you want to target you would go to 'demographics' and there you can select the type of home you would like to target by size, value, type of residence, etc.Let me know, if you have any questions, mate!

Can you give me an idea of area/towns, typical deal size (including acquisition and expected rehab budget), timeline for rehab and then for sale, etc? 

Is there a certain size of transaction where these become more relevant as I am dealing with modest single family homes making a profit of $20k - $30k.
