@Ali Aldhanhani - Hi and welcome Ali....  1 - On a standard real estate investing calculator "vacancy" is expressed as a percentage rate and is understood as a "negative income - or expense" - and helps you be realistic about the amount of rental income that you can expect from that unit during the year.

Stove, Fridge, MW, DW, Range Hood (If any), etc.

I have searched far and wide in BP and Google and while reviews may be helpful, no one has given a solid recommendation aside from few on the forum.

PM fees should be more in the 10-12% range.

The suggested immediate repairs are in the $30k range. 

Combined with a brokerage account such as one from Etrade, they have access to a wide range of investment options although sometimes representatives at brokerage firms misunderstand the flexibility of these plans. 

I know a lot of lenders do not lender under 50k and if you go into the jumbo loan range in your area, the rates starts going up.

I am in the DFW area and do know that we have a decent range of prices.

We own several in that size range, 16 units, 23, 27, 41. 

The percentage can range of 3-5% all the way up to 15-20%.
