Earlier this year we replaced the original water heater (I am sure the new one wont last 33 years).They will be gone as of September 30th, then begins the rehab and renting process. 

There are some unique things you can do on remote rehabs, but you do need someone on the ground to be able to put eyes on it.  

My partner and I just finished our first rehab project and I've been getting generalized invoices.

I recently inherited a 4-unit apartment building free and clear. The property needs to be renovated to achieve maxium cash flow. My credit is not good...any advice would be appreciated.

Private money would be even better because it would be less expensive.Do you have any experience doing rehabs?

I guess I am assuming that if I had a pipe burst they would say my plumbing was too old (which it is, will rehab the place when the current tenants move out).

First, you should have known your leases were up for renewal, and addressed it.Second, the buyer should have required estoppels for the leases, most don't, but your listing data Definitley should have shown lease periods.Third, we have no idea what your contract says about this, nor what your listing information detailed.

Whenever you need help getting started, don't hesitate to reach out, I have a strong connection with a hard money lender, and I personally sell investment properties in need of rehab.

When you are seeking this information, be sure you compare rehabbed (flipped) houses versus traditional sales.  

What's included in your rehab budget?
