I am by no means an expert in international Tax, but selling homes in Texas couldn't be easier.

I think you're aware the PM fees for STR are on average higher than long term rental PM fees (it's just more frequency of work), but really it's going to come down to city legislation and the building condo association. 

However I expect Legislation will be drafted by states to deal with the significant number of evictions that will add additional roadblocks for landlords. 

3) As an international OOS investor are there restrictions?

Whether or not an item of income is subject to US tax depends on the internal revenue code and the relevant tax treaty (taking into consideration any applicable savings clause in the latter).It sounds like this isn't a residence. 

I would be willing to make sacrifices or deals with the company in order for a chance to learn.Would a company be interested in hiring me or letting me intern?

Title search, back taxes etc all come in here as well.If you've covered any major defects, established rehab or updates needed in terms of cost, run accurate comps, verified tenants/PM's if this applies/they want to stay, verified zoning if it applies, tax rates/title work, local landlord legislation for buy and holds, and the terms of the contract, you should be ready to rock and roll = ) Hope this helps!

I started with commercial NNN as an intern, moved to residential when I got my license, and recently moved into my current position as a licensed assistant for a senior apartment broker at Marcus & Millichap.

It looks like the students are coming back to Boston, but questions still surround vaccine requirements and international student mobility. 

I would also recommend interning with a local RE investor in the area you are the most interested in if possible.
