If you have $50k to invest then you will probably be looking at properties in the mid-to-high $100s (assuming you're putting 20% down + closing costs and a little cushion).

Generally, I would recommend giving your Airbnb at least 6 months to build some credibility.

If she starts acting up, tell her to leave the room and if not, tell her you are going to start recording the audio on your cell phone.Is she on a lease or month to month?  

If you have, say, $30K in savings, what you should NOT do is spend all of it on some random property that shows in a spreadsheet that you'll make $102 a month, and then you buy it and get crushed by repairs and maintenance. 

Honestly, I've been getting screwed with some big ticket issues (related to HOAs, selling different properties, continual unforeseen maintenance and costs) and this one really crushed me once I realized it was an actual issue.

Here’s the information$800,000 commercial propertyno down payment 30 year contract at 7% percent fixed.Mortgage is$5,700There’s a small vacant space on the back that you can possibly build a mechanic shop bay on and make some additional income maybe about $2,000 a month.On the front of the property their is a small building that has a restaurant and they pay rent $4,000 a month. 

I'm a new host who started hosting about two months ago, and I recently listed my property on both Airbnb and VRBO, approximately a month ago.

The hardest part of the deal was finding someone who would finance 50K for 30 years and be ok with making $1.48 in profit a month.My mortgage payment was going to be $312 and this house, by my estimate should rent for $1,050/ month - which it did.

How about “ I know the multi family market data well and its a great time to buy rentals because interest rates are above 7% for 30 year mortgage and people don’t have 20% down payment to avoid PMI for lower monthly payments.

If the property can be sold, pursue a short sale for its current value whatever that may be after considering the cost to remedy these issues.
