So many dependent on government.

If you have one of the older, turn of the century mid town houses, you are probably getting somewhere around 1600-2000 depending on the condition of the home, availability of a garage, etc.It is an older home, from the 40s I believe.

Of course this all depends on YOU setting the base rate and all the knobs and triggers most appropriately.

@Jason Sinclair, having a designer for a wife, I would answer that it really depends heavily on each house, the flow and usability of the spaces as they are, and the overall use of space in the house as a whole.That being said, while there may be a small shift towards more separated spaces, "open concept" is by no means dead, and in many markets, most people seem to still want to have connectivity between their communal spaces.In fact, my wife's current flip is a split level (although technically it is a split-foyer), and she is taking out a structural wall to connect the kitchen, dining and living areas.  

Depending on the loan product, you may be able to exclude business debt once the business has paid the debt directly for 12 months.The income and losses related to the operation of the entity will affect the income side of your DTI (like Jay explained) if you own 25% or more of the entity.

Collecting rents is an art and a science.What you should depends on where they are with their late rents.

The choice between JVs and syndication depends on personal aims and interests.

Most PM's here charge 15-20%, most are 20, but will depend on what services they offer.

Depending on the price point, they may already be running targeted ads in cities/metros for buyers that may be looking for a second home/vacation home.

If it is someone you know you can give them a straight return as if its a loan - can provide a lower interest rate to provide upside - it really depends on the lender and what are they concerned with and what is their risk profile.
