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

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

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. 

I'd recommend to first look at where you'd like to invest it to see if it's feasible or if you need to adjust your buying criteria.If you're not in the market for something new then I'd look into adding an ADU on the lot and upgrading the windows on the main unit to triple pane glass so that the noise doesn't bother your future tenants.

My rental has a lot of extra space outside around the house to consider doing a ADU build and create additional rental income.  

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!

I don't think I would add extra cash into the deal to buy down the rate, if you have extra cash I would consider doing a 25% down payment, that will usually get you a better rate/terms.
