For instance, FHA guidelines are very strict and restrictive when it comes to using departing-residence rental income to qualify for a new FHA loan (such as the 100-mile rule).

I can't remember exactly, but I believe the main ones had to do with additional parking restrictions and water.

But usually for a tenant occupied it's like $90-120 per monthI've noticed a lot of multi-family buildings are pre-WWII housing inventory - are there restrictions or issues common with that (historic districts, crazy high utility costs, etc)?

Im open to conventional financing or seller financing.To find properties, you can network with local agents and brokers, join local real estate investment groups, use online platforms like Zillow, Realtor.com, and Redfin, send direct mail campaigns, drive for dollars, network with property managers, and explore seller financing.Good luck!

I had a similar off-season challenge and decided to allow pets ( with restrictions and clear house rules) and I gave a 30% discount to try & attract  snowbirds ( I’m in FL) - my calendar filled up for a few  months with a few pet owner bookings and  2 separate 45 night bookings,  did all this on pricelabs & airbnb -best of luck ! 

But the neighbors told me when they built their house from ground 6 years ago, there was no issues for any building materials or trucks going through the alley. 3. the house is in historic district of Charlotte, meaning there are quite some restrictions on the exterior renovation. 

Same goes with restrictions on equipment.

The city just passed a very confusing zoning regulation restricting student housing to a specific area, and we're all trying to figure out what the fallout will be.

Realtors often claim they're restricted to Realtor use, but that is incorrect. 

Also, make sure there aren't additional restrictions on the property condition, compared to a conventional loan.
