We are looking to do this versus a home office deduction, which we probably wouldn’t qualify for anyway (would fail the exclusive clause).I’m sure this question has been covered before in the forums, but I can’t seem to locate a specific thread on this topic.

Do you have specific markets in mind for the duplex?

When buying an investment property would you advise to sign as co- signer with your spouse?

It is landlord-friendly, and specific pockets have gone upwards of 2-4x in the last 5-10 years.

I'm not sure the specifics of that market but my initial gut reaction would be that 90+ day stays may be a bit too limiting to make an MTR worth it. 90 days could work well with the average 13 weeks for travel nurse contracts but may limit your digital nomads, business traveler, etc bookings.

Each has specifics, such as...houses newer than 93..can't back up to power lines...no retaining walls...etc.

But are there any specific loans I should aim for?

I don't have any specific goals set yet.

I can think of other examples and that's probably not the best one but I don't want to get into to many specifics. 

Changing architect and contractors in the middle of a project are not easy and not advisable.
