Despite the previous owner raising rents last month, she is still falling short by $5,000 each month.

I paid almost 40K in interest last year. #2.

This is where I would start if I were you—perhaps leveraging one of your existing properties.As a last resort, you could look for a partner willing to fund the project in exchange for a share of the equity.

What if they change the terms on you last minute?

I would be curious as to what your lease says, and if the parameters consider something like a pest problem, your responsibility or the tenants responsibility.additionally, it is hard to find a quality tenant that is going to be a good steward of the home and will be long lasting with the longevity aspect, especially for that price for an apartment. 

However, given the fact one is gone and the other is doing their best to cover all the rent, eviction would be a last option.

Quote from @Andrew Swaim: hey everyone, I have a couple investment properties but i have never found a awesome discounted deal, the last BRRRR i did was just alright, i started using deal machine but all my cold calling is coming up empty, the wholesalers in my area have been sending out crap.

Fixing the inside of the house is usually the last resort.Regarding disclosures, it wasn't like the sellers were able to pull one over on you.

I had a tenant do the same last year.

Comps in the last 30 days sold between 90,000-100,000.Any advice on what you guys think would be the best thing to do?
