I run a call center for Real Estate and its all about knowing your numbers (100 dials to talk to 10 people to get 1 solid lead to convert in 6-12 months).

I am looking to purchase a single family home which has 2 bedrooms, kitchen, living area, bathroom on main floor. The upstairs has a separate entrance, then 2 bedrooms, kitchen, living area and bathroom plus a door go...

And lastly, are you able to convert it to duplex?  

Converting the sunroom into a bedroom would cost 4k-5k. 

We won't make a loan if it does not look like the rehabber can earn a profit of at least 10 to 12% of the ARV, converted to dollars, of course.This approach takes both your profit, in dollars, into account as well as the value of the property.

Likely will not require permits or consultants $45-$65 per sq ftFull Rehab: This includes all of the above, and new systems, new roofs, windows, some siding, non structural or minor structural reframing, finish basements, convert garages.

When the market is more balanced, then it may make sense to buy a primary and convert it to a rental when you move.There are exceptions, but you will need to learn how to really analyze a property to know when the numbers make sense.

My company is experienced and great at converting leads.

Once the house is done, the loan converts into a standard mortgage.

Our goal is to convert it back to a 3-4 unit property for long-term and short-term rentals.As I currently reside in Washington DC, I'm unfamiliar with the local permit processes and requirements.
