As an extra level of protection You could try and save up a few months of what the potential mortgage will be to give you peace of mind. 

So you don’t get to pocked all of the extra.

Those might make good rentals...but also there can be extra costs...see if they are in PIDs/PUDs or MUDs that add significant cost to the monthly payment...maybe $100-$200 extra a month.Also $2500 sounds high on rent to me for 1800sqft....I would think more like around $2000/month, but haven't looked in that area lately.I do like Forney....one issue is I don't think there are good demand drivers there. 

Otherwise, look at side jobs you can do to earn extra money. 

This works well for wholesalers who sell deals to flippers, and flippers or investors can benefit even more by going the extra mile to generate their own off-market leads.

After he implemented the RUBS, he actually reduced the rent a bit to enable the user to adjust to the new extra billing.  

They quoted an umbrella policy for $200 extra, which is very reasonable.From my limited understanding of insurance policies, if I have the second-home policy with home sharing endorsement (personal liability $1M) plus an umbrella for $2M, then I should have about the same coverage I get from Proper, even in the unlikely event of an off-premise liability lawsuit. 

Because I wanted that extra money for real estate.

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!
