You can also expect increasing HOA fees, and there may be some problems renting a property inside a difficult.You don't have any experience, prices are at an all-time high, and rates are also high. 

Depending on how it is done and what guarantees the government offers and requires of the released entities, interest rates could move slightly higher.

I am seeing a lot of AirBnBs already with high ratings for location 

The interest rate isn't that huge of a difference between the 15 and 30 so worst case scenario if you have the 30 year option is you start paying it down on a 15 year timeline - sure you'll pay a little more in interest over the 15 years, but it will have been worth it if you bought another house.

I have some YouTube videos that may help with some of your questions and always happy to have a call to dive a little deeper. 1. which development(s) tends to be the best for ROI/have the best occupancy rates? 

Interest rates are changing every day. 

Currently living in our home and plan on renting to keep low interest rate while we house hack a duplex to start our investing in real estate.  

One other advantage is that many of the builders that I have worked with are able to incentivise the sale with interest rate buydowns that make the deal work.Best of luck moving forward. 

It seems like everyone is preparing for a big boost.The current growth rate seems feverish but I've seen a lot of houses going up to prepare for the influx of population.If you have any questions, I'm available to answer them.

if you miss your rate lock timing and it costs you to relock who should pay for that?
